The purpose of this game is to create original sprites in a cooperative effort, not to constantly morph it into something else; there's already
another game for that. You should be adding features or refining things already there, not removing them or turning them into something completely different. If a sprite has come this far and the only changes you can think of completely change the design, then it's probably time to start a new sprite.
(not that I'm in any position to hand out a reprimand, it just seems disrespectful to the people who made the parts that you've removed)
