looks cute but u might want to look up "banding" in the tutorials coz u got some pretty hard-out staircase banding going on here.

I really like these world select icons.  The style is simple but they are really clean and colorful! My only major complaint would be that you have a bit of banding.  You could resolve this by reducing the color count and by differentiating your shading (that is not mimicking the next shade pixel for pixel).  I'm eager to see more.
