The designs are pretty sweet, very interesting look to them. The first two have a black outline around them though, which I think flattens them out. And on the last two, it looks you painted the highlights with white, or a lighter version of the shadow color which makes it look chalky. Vary the hues a bit when you're painting the light and shade. Hell, vary the hues a bit throughout your illustration, a little variety can make a surprising difference.
