Nick's Pixels'n'stuff

What 1up/HtE was saying is that you use lines and clusters that have 1px clusters/thickness in them, which creates noise (jagged lines, sharp edges, dots, etc).
You've got rid of most of it but there's still some there. I made an edit to boost the contrast between elements:

The animation looks odd because the feet movement and the bobbing of the rest of the body don't make any sense together. Why does the other hand pinch the air? What's happening to the crown? You'll have to work on a way of making it all synchronize together in a movement, and not individual parts.
I hope it helps!
