Need some help here.

This guy looks much more natural than before. Nice improvement on the shapes. The issue this time, though, is banding; the shading is following the outlines shape, giving it a beveled look in some places and a gradient in others. It's understandable for the cylindrical helmet, but even that can be fixed my baking the shades more than a pixel thick. A good idea is to start by picking a light source; for instance, my sprites are all lit from above and slightly in front. This guy looks like he's lit from directly in front, which only makes sense if he's holding a light source, like in the Kirby games when you hold flashing orbs for certain attacks.
