Yes, more like that looks nicer. You may also want to check out, can't remember who came up with it now :/, a technique called vecxels. pixels mixes with vector art look.

One thing you really need to focus is on line quality. As I see it its your main hurdle for now.

I agree but the character works over saturated. This in cell shading style would look awesome.

way too saturated colors for my taste.
