I got a couple more done earlier today:







I think I've improved a bunch even in the few hours I took to do these three new ones.

As always, any feedback is appreciated.

zombie one might look better with more missing flesh/parts. the shading on some of them looks a little flat, still, especially the ninja (could be fixed just by making the shadow tones darker?) and around the neck on some of the others. overall, they look good, digging the style.

The dithering advice makes more sense in the context of the actual advice. But the crit is valid, there's too much dithering on several of these. Dithering is really something you only really resort to when you're out of other options.

In general I'd say more contrast, your hues are too close together. And because you lack many strong darks, the jump to black is pretty stark. Some indication of separate toes would also be neat.
