very cool and nice detail, tho shading on the armor looks pillow shaded and the feet look out of place
The black lines tend to be pretty harsh on this pice. maybe try some smoother lightsource-based outlines. Also parts of it seem pillow shaded with the gold. there is also a lot of banding present as well as a severe need for aa. now that that is out of the way, id like to complement the design.
Good job, but I think you stopped too early with this piece. You could have doen so much more with the lighting. The line art is pretty good, but the head, neck and face could be better, I think.
Nicely done, as an eldar Player Ican only like.
