There's a couple of changes I'll recommend to make to the character. They're all set to make the character more powerful, but depending on the concept you have for the character you are free to ignore them. I also suggest looking at Umaro's Archetypes. I discuss his mage archetypes
here. I suggest looking at their spell lists and general builds.
How do you feel about being a shaman? If you can be a Intuition tradition such as Wiccan, Druidic, or Buddhist, you can avoid the charisma and logic penalties orks get. If you want to stay a shaman, I'll go Elf.
First off, I would sell back Strength to 3. 3 is an acceptable Str value and you are a mage who really doesn't need Strength. Since you're be casting spells in fights rather than pistols or knives*, I'll sell back agility to 2. That frees up 40 BP. I would soft-cap your non-Willpower casting attribute with the saved points. That should be 4 for charisma or 5 for Intuition.
Now for your skills. You don't need Astral Combat. Your astral move is stunbolt. Your meat combat move is a spell so I'll drop Blades and Pistols. That saves you 24 more BP. I'll buy Spellcasting up to 6. I'll also buy Summoning so you can summon Water spirits. You'll want to be able to roll 10 or so dice there. You may want to specialize in Combat Spells and Water Spirits as well if you have plans for your karma. I'll also buy counterspelling to 4.
I don't like dodge and recommend dropping it. It only really helps in melee. Perception should be increased to 4 or dropped to 1 to avoid the default penalty. If you're Intuition, I would err on the Perception 4 side. You'll be the party spotter.
Do you need to be a hobgoblin? You're getting fangs for Poor Self Control and a distinctive feature. That's a bad trade. I would be a normal Ork with poor self control or be a SURGEd Ork instead.
How do you feel about Shark as a mentor? Shark's berserk will likely come back and bite you big. There are other +combat mentors such as Sun.
If you can afford it, I would recommend a Force 4 Power Focus. It's a quite decent deal at creation (even with the Restricted Gear Quality) and is a huge boost to magical power.
*-If you want to a agility superstar, you might want to look into a Heightened Concentration Mystic Adept build.
