There are a few things wrong with it, but it's pretty good for a fourth pixel signature (I'd hate to show my first few around here...) First, I'd change the shape of the top of the tree, and the lemons. I seem to remember lemons not so circle-y... I'd also change, and edit some of the colors for the tree and tree top. The grass is good, but really isn't distinguishable. That's just some of the C/C, but anyways, pretty good for a fourth one, compared to my first ones.
