Thanks for your comments! I will keep up the work with this sprite and take your advice in account. I agree with you (pawige) about the colors, one or two of them had to be added late in the process since I had choose a bad palette from the beginning...

I agree wih Pawige, especially about the skulls: with less dithering they would have more depth. But good nonetheless

I think this could be improved a lot if you dropped most of the dithering. You could smooth everything out, especially the body, to get more solid forms. Also, you've got a couple colors that are rather close to each other in brightness, I would try to evenly space them out a bit more, you'd get a nicer overall look. I like the cracks and damage on the wings, the skulls are cool too, though they would also benefit from less filler dithering.

Awesome job. If the tail would have tapered from thick to thin and 'pressed' in slightly more into the skulls it would have been ever better.

Great stone texture.
