Cool! I like the Staff

It's an alright character concept on its own (decent birdlike features and pose), but it doesn't seem very Warhammer Chaos to me.

Being careful to criticise it and not force my opinion on you, the other Chaos daemons look more sinister and have corrupted forms. This character, whilst I can except you'd want an elegant birdlike form, does not look very evil or scary. I'd probably adjust the expression - either giving it a vicious snarl, or give it sunken eyes.

I would give you 8, but I'll give you 9 in case my score is tainted by personal opinion.
