Moebius has some wonderfully detailed work, especially with some of his background work. Thank you for the comment :)

I like the line art, together with the color choice it reminds me of the late 70s comics, Moebius specifically.

Thanks for the input- the gradation was a complete after thought and added in after I all the hand pixels. It added a cool effect,  but really wasn't necessary. 

This piece seems to have some automatic gradients in it, it uses a lot of colours, even though a much smaller number would look the same. You may want to clean that up. In this case, automatically reducing it to a palette of hand-picked colours would probably give you perfect results.
