Thanks for the feedback!
I fixed it up a bit according to what you suggested. The colour count is now at 15.
Cute little sprite. Welcome! =)
Nice colors, but there's too many, since some are undistinguishable. You might try to bring it down to 16.
The shading is also somewhat random and doesn't really convey volume.
Very nice dithering and colors, but a couple of tones feel off
