I like the costume design you have going. I also like the fact you kept him human (because human Smoke is teh sex), and that you gave him spikey hair. *is a fan of the non-traditional ninja look*

Just a few things for you to work on. His head is a bit too small for his body. The same with his hands. Just flesh them out a bit more, and it will look much better. Also, don't forget shading. Shading adds tons of body to a picture, even if you don't think the picture is that great.

Hmmmm.... better then I can do.. a little bland for some reason, But it's pretty cool. I like the changes you made to the traditional MK3 ninja costume.
