Edit: I've updated character builds according to thread discussion and further ideas.
This is the tentative draft of my first DFRPG character, done in two slightly different versions that draw power from opposite mystical sources b/c I cannot make up my mind about which one I prefer. To help me shape the concept I developed it in several different power levels ranging from 10 to 21/22 Refresh; however I assume the concept requires at least 15/16 Refresh to be any barely realized and 18/19 Refresh to have all required features more or less in place. Everything below that is just preparatory work. I welcome constructive suggestions and opinions, especially as it concerns Aspects and their wording. 
Notable concept features that may be Aspect-worthy include: being a half-sidhe changeling and a sorcerer/wizard; drawing power from mortal magic, Faerie, and Lower (or Higher) powers without becoming any especially evil or righteous; being eager for mystical (and martial) power and amoral with it (and violence) but not really unhinged or corrupted by it; being brash, hot-tempered, and rebellious to authority but honorable and loyal to friends; often doing the right thing for various reasons but being no kind of moral paragon; being good with flashy, freeform magic and martial arts but bad with subtle, ritual magic and technology; being plagued by an hyperactive Murphyonic field and/or a magnet for mystical weirdness but not having other kinds of bad luck; being the chivalrous kind of lech; being a biker.

I avoided to buy Soulgaze despite being available for free since I deem it more trouble than it is worth. Conversely, if the character could have even more Refresh, additional powers that would fit the concept include: True Shapeshifting (NOT Glamours, despite Faerie ties), Swift Transition, and Wings, as well as removing the Item of Power limitation.
