The entire thing kind of missed alot of outlines, you can just use black for the entire sprite's outline or a darker color from the pallette rather than leaving it empty. Maybe applying some dither would work too. Anyway, it's good.
lol cute! It could maybe use some clean up on the jagged lines and a bit more shading to drop the furthest head back etc. Overall very very good character :D
Haha, this is very funny! You could have made the pixelwork better easily by cleaning up some lines, but the funny faces and king make up for it :)
