First off, get rid of the sel out. It's rarelly ever good. Either cover the entire duck in an outline, or don't outline. But don't outline partially, it looks jagged.
Secondly: Your textures always seem to be a bit messy. Why don't you try giving them a somewhat cleaner look? I'm quite sure it would look excellent on cartoon duck.
Furthermore I adore them.
