yeah! Nice work perfecto - this is looking very cool - i really like the wings - and I think once you have added all of the shuriken stars and katanas, this will look pretty evil!

i must admit i think it's a shame that you're not sticking to the four arms design - with a weapon in each hand and him flying through the air like in your concept - that would have looked really cool! I'm sure you could make the anatomy work - after all the wings are just another set of hands as well.

either way this is shaping up nicely!
