This time I think I'm done with it, I've tried to work on different textures: scales, crystals, rock, fire (dithering, I know I love you a little to much). 16 colors Inspired by the universe of Planescape Torment, pure video game masterpiece.
I've tried to modified it, not sure if it was exactly what you said. I don't know if I can work on darker tones on the legs anymore, I fear a lost of the coherence with the bust. Thank you, it's really difficult to have an overall vision on a pixel art after so much time on it, so comments help a lot
