Mario and Luigi were the best improvements. I love how you can see their whole back now, along with the fact that their caps aren't just circles anymore. Everything's looking amazing so far, and it's great to see you back on the racers as well. The only criticism I have is that Bowser's bigger arms in the back sprite make his legs look tiny, and Peach's victory pose arms are oddly shaped and not very visible from a far. Remember, she throws the campaign bottle in the air, there should be more emphasis on her arms (even outline may help).
Also, I have a question. What was the reason for stretching Bowser's mouth more?
