like the concept, but you seem to just be adding more stuff not listening to peoples critiques and repeating mistakes they have pointed out. the last 3 screens especially, inconsistency in bboy red's legs as in the top they are not outlined, doing footwork theres a black outline and the legs seem like twice as fat and arms twice as long. Same with wiggles' head spin, his legs seem nearly twice as long.
from a bboying point of view id say make the head hollow leaning over more, cause right now just looks like a headstand.
My suggestion would be to revise the original sprites using people in this threads critiques, before continuing on new characters etc.
