Great project! I'd like to tell to everyone who want to start drawing pixel art, I built a very simple tool to get started with this technique: http://drawbang.com.

I definitely need a right-click colour picker (or shift-click) to work more easily. Can I suggest cutting back your GUI, removing that 3d look, or if you like it too much, then making the pixel art pictures also be 3d like that.
