I think these attacks would feel pretty laggy in a game, maybe speed them up a bit? Also, this strongly reminds me of Eddie from Guilty Gear.
This reminds me strongly of a game called The Darkness for Xbox 360.
I'm not sure how well the external AA works on darker themes.
The animations, and attacks are good, but the character its strange. Try to improve the shading of the hair and clothes.
i like the concept but the animation seems alittle slow for attacks. also i agree the character needs alittle work.
