Thanks for the helpful critic PypeBros (ohhh I get it)! I shrunk Luke in general, including his shoulders, and changed up the colors a bit. For Luigi I only changed 2 pixels on his shoulders, do you think it did the trick? Their noses are very important, but I just can't think of how to pixel them with this style, any advice would be welcomed.
I also added Link, first attempt at hair and a slightly different face. I think Zero Suit Samus is next.
