uhmmm, well. It's hard to actually see your black outlines against a black background. I'd suggest using a grey background, since it's a pretty neutral colour.
I wished you would have picked colours that were closer to the original scan, right now they seem to be too cold. Especially the skin, which is too pinkish.
Your outlines also seem to be a bit inconsistent style-wise, his nails, hair, sandals, belt have this very round and sloppy outlines whereas the rest of the outlines are sharp.
Keep up the good work.
