I agree with odedrt9, I think that heavy black outline has got to be reduced. I feel like the anti-aliasing makes it too fuzzy. I would really look at what Seiseki did with line weight and apply it to a thinner line. Also, given what was said about banding, maybe instead of hard black (which a lot of times is discouraged anyways) for your main outline, do a darker version of the nylon's outline.
