I just realised you already posted another thingy a few days ago so i checked that out too. I'll post my 5 cents aswell i guess.
Basically I guess the first thing i would like to see changed is when they hit each other, there should be some fire smoke blood and all the good stuff like a real fight on every attack. Go for transparent hitsparks like what you find in the JUS mugen characters. If you look at some of the cool ones like the Naruto Kyuubi or The Goku edits you will see what i mean. Every kick and punch should feeeel and look cool!
