This peice has only 8 colors plus transparency, not 11. You have plenty of room to make the dress a more oceanic blue.

Also, actual black can work against you as some programs will read it as alpha. Try a dark green that is indestinguishable from black to the naked eye.

I love the anti-aliasing on the trunk.

This is really smooth and reads really well. I really like the fact that the legs are thicker.
