Recently, I submitted this sprite sheet of Chuck E Cheese to TSR. It was rejected for "not meeting quality standards for the Custom / Edited section". I would like to know how to improve it. It is based off of how Chuck E Cheese looked in the early 1990s, and is styled after early to mid 90s MS-DOS games.

Thank you for pointing out the issues with my sprites. I will address those sometime later this week, most likely tomorrow. Also, by Chuck's mouth, do you mean the red used for the inside of his mouth, or the whole skin color area around his mouth?
