Hey there Vakte! 
Just a heads up so you don't have to rewrite too much stuff, werewolf characters have been attempted before, and Dervish is extremely selective about them and will nitpick your CS until it's perfect. To my knowledge, no werewolf sheet has ever been accepted. 
Probably the most important thing to consider when writing your CS and planning how you will play him, is how a werewolf would be viewed in the eyes of the characters, I.E. They would fear him and probably try to kill him if they found out before a good trust had been built. 
Don't expect to use your werewolf powers very often, if at all, for quite some time.

That said, after seeing your writing ability in Nova, I say go for it.
