Re: Show of your custom characters!
I reject the idea that noobism in spriting is something to be celebrated. I believe that everyone has potential, and such sprites as that are merely the gunk clogging up the tip of the talent hose. Get them out of the way, and don't think that you can never be good, but DO NOT act like the gunk sprites are worth anything. If you think they need improvement, IMPROVE THEM!
Philosophical argument aside, it's not the worst I've seen. Has too many colors, that seem unconnected. Try making it simpler, with some shading (e.g multiple shades of each color used). And learn what antialiasing is, and use it.
