Point buy is needed for power focus F6 but being an aspected sorcerer is limiting oneself in my opinion. If you do it for RP reasons, then ok. I don't like point buy so I tried making your character in priority (nearly always better). Result: some things better, some worse.
Now full magician
but only combat spell focus
Very sad because this version could use a Power focus for summoning too. If I were not going for max combat spell dice, and using this character myself I would go for the Power focus rating 3 and have karma to spare. (no Restricted Gear).
Priorities: Magic A, Attributes B, Meta C, Money D, Skills E
Attributes: Bod 3, Agi 3, Rea 4, Str 2, Cha 2, Int 6, Log 3, Wil 5 Edge 7, Initiative 10+1d6
Better Intuition results in more initiative, more drain dice and better skills
Positive Qualities: Restricted Gear, Revels in Murder, Witness My Hate (same)
Neg Qualities: Choose 25 points.
Skills: No pistols but the important change is trading ritual spellcasting to Summoning. Real Spirits instead of watchers and homunculi! Spirits of Man can even cast combat spells themselves!
4(6) Unarmed Combat 1+spec (Touch)
12(14) Spellcasting 6+spec (combat) (22 dice for combat spells!)
12(14) Summoning 6+spec (Spirits of Man)
10 Assensing 4
10 Counterspelling 4
7(9) Perception 1+spec (visual)
3(5) Etiquette 1+spec (Street)
3 Intimidation 1 (with karma)
4 Computer 1 (with karma)
5 Pilot Ground Craft 1 (with karma)
Gear: Spellcasting Focus (Combat) rating 8. 18000 left (+extra if in debt is choosen)
Spells: Death Touch, Mana Ball, Mana Bolt, Power Bolt, Combat Sense, Heal, Increase Attribute (Charisma), Inc Reflexes, Imp Invisibility, Physical barrier
Watcher and Homunculus no longer needed. Increase charisma is broken useful. Inc reflexes is good.
Karma: skills 6, Pos qualities 25, bonded focus 16 (3 left to spend)
If going the Power focus rating 3 route I would lower Assensing and get Binding + a specialization
