All of Ark's advice is good. In addition:
You seem to have paid for RG three times, but only have 2 foci that are high enough avail. to require it. Also, the monofilament whip focus is not a good idea. A variety of spirit types - including in particular Fire - can generate much better unarmed melee attacks than they can do with the whip. Engulf + Energy Aura = F+4 DV, plus the ongoing damage (note that Guardian spirits, the only type that can be proficient in the whip, don't get Energy Aura). You would be better off not having the whip.
Astral Combat is largely for silly, and you suck at it anyways. Just stunbolt people.
Trid Phantasm is an excellent spell and you are an Illusion specialist, I recommend it.
Stunball and Orgy are a bit redundant.
You can get a f5 sustaining focus rather than an f4 with Restricted Gear. If you're coughing up for RG, I suggest going full monty.
The only social skill you have is Con. Consider dropping 1 charisma and having more Con instead.
I think your armor is loopy - you want to shoot for 10/10 for encumbrance, which means FFBA plus another 7/9 of stackable stuff. You can jam on a bit more if you are willing to use Softweave (from WAR!). Vashon Island plus 0/2 of PPP is one option, so is Urban Explorer plus 1/3 of PPP.
The Monofilament Whip itself is availability rating 12, so that's what the third Restricted Gear is for. I realise I'm probably going to be shooting myself in the foot a bit by focusing on Guardian Spirits to be able to use the whip, but it's part of the concept. I'll look into Spirits and their skills to see if the numerical advantage can't sway me after all, though ^^ Spamming Engulf with Fire spirits last campaign was very nice, but that's also one of the reasons I'd like to go a bit different this time.
I'll drop Astral Combat.
Trid Phantasm is on the list of spells under consideration ^^
With all the BP I'll be clearing up, I should be able to get that Force 5 sustaining focus.
I'll go for more CON, but I need some charisma in order to bind more spirits and resist my mentor spirit's influence(it's a will + cha test with a threshold or 3 to not give in to a vice(drugs, alcohol, etc) when presented with it).
Orgy is in keeping with the theme. She's basically subservient to a pleasure demon(the seductress mentor spirit) and all of her summoned spirit are linked to that as well, so I found it cool that I could cast orgy to make everything(such as possession by these spirits) easier.
I'll check out those armours you suggested and if they're reasonably close to what I'd like my character to be wearing, I'll get them. I'm not that bothered with getting the absolute full bang out of my buck in that respect, I've already checked out how resistant I'd be with a demon possessing me, and it's so high in comparison with our last campaign that I'm a bit worried my GM will have some problems with that :p
Also, she doesn't call herself a seductress, I do ^^ I'll up her CON though, no worries. I would like to point out though that 3 CHA places her in the average range for the stat, while 1 rating + specialisation + seductress mentor spirit places her at the equivalent of 5 rating. Rating 5 is described as "Social Example: Incumbent politician, Grand Tour regular, corporate vice president."
Compare this to rating 0: "Social Example: The typical man on the street." I'm assuming this is also the typical woman on the street.
So before you call her unenticing or go "lol, seductress with those stats?" take a moment to reflect on the fact that just about every girl you ever met was, on average, 5 dice less skilled in seduction than she is.
Especially with the prejudice. First fails to seduce about anybody, then blames them being prude and gets physical. A troublesome combination.. but maybe you were looking for it.
I find this thought amusing indeed, but purely by RAW she isn't -required- to get physical. The entry only assigns each category with a threshold to resist seeking a confrontation of any kind, it doesn't state that Radical means you have to respond with physical violence, for example. She'll be plenty vocal in her dislike, and won't hesitate to get violent if she can, though.
Slapping a guy in the face in some bar because he refuses your advances will probably not get her into trouble :p If it's some dangerous gangster boss then, well... I guess we've just made the campaign a little more interesting, then! My teammates will probably want to look out for that more than me, though. If I get myself possessed even with just a Force 5 spirit we'll be looking at a body of 10, ballistic armour of 10 and immunity to normal weapons 10, with a dodge of about 13. I feel quite confident I'll be walking out of there unless they all happen to have brought their LMGs that day and they draw and shoot their gun in less than 3 seconds(though in movies it's usually: everybody draws their weapon "What was that for, bitch?!?", then a response, then pew pew pew. Plenty of time) :p
edit: So I'm in the process of reworking the sheet, I've included a great many of your suggestions so far, I'll post the finished work for re-evaluation once done. I'm currently mostly looking into my spell choices.
-I decided not to look at the concept as "good at illusions" but more as "good at affecting people's mind/bodies". Because of this, spells like Invisibility, Mask, Orgy, Influence, etc make sense to me, but Phantasm is somewhat outside of the concept, as it creates something instead of manipulating it.
-I mainly took Ignite as a way to get both single damage, and put stuff on fire. Looking at the object resistance table, this seems harder than I thought, so I'm up for dropping it.
-How strong is your suggestion to swap stunball with stunbolt? I think I could hit the enemy without hitting allies most of the time, and even if I can't I could use another spell(such as control thoughts, maybe?) right? Then again, I could also take stunbolt and use different spells(like Orgy, I just like the idea of the spell, even if it's perhaps not the best spell around ^^) for areas, I guess.
-I definitely must have either Influence or Control Thoughts as my 8th spell, they look sweet. In fact, they look so enticing that I may like to have both, as they seem useful in completely different situations. To that end, I'm willing to switch out Ignite with Control Thoughts and take Influence as my 8th spell. Do you think this is a good idea? Someone mentioned taking a good elemental spell to fight vehicles/drones, I would be foregoing that with this, which would of course reduce my options against those foes(though control thoughts on someone piloting a vehicle could be -very- nice ^^). I have teammates as well of course, no need to do everything, but if you had to pick an elemental spell for this purpose, which one would it be? They seem a bit expensive DV wise to me.
Also, if I do end up taking both Influence and Control Thoughts, should I switch my specialisation in spellcasting from Illusion to Manipulation? I'd have a +2 to illusion form the mentor spirit still, and as the theme moved away from straight-up illusions to illusions that have to do with people + thought manipulation, having both at the same value may fit more.
