Great and original looking ninja. I have to agree, the shading is flawless. The right upper arm does look a bit off, short and it seems to be in an odd position. I do enjoy the fishnets though, good work.
yeah- I used to love ninja gaiden before MK, so I kind of based my design off some old NG designs I think... heres a basic colorization I did a while back. I left him in white garb...
