Ocelot, Take 2

I attempted to color my ocelot sketch on the computer for the first time. I don't think it's a complete flop, but I don't think it's a complete success either. I really want to learn how to do digital prints properly, though. I think using a clear marker and avoiding shading would help me get a cleaner line on my next drawings, if I do try to draw something to color using Photoshop again.

Does anyone have any advice for digital coloring?
