I really like the look you're going for in crystal. It's fast and fluid at the same time. Although you seem to do a spin with both shoulders raised a lot, try to add more uniqueness in your movement(not that it isn't, but ya know, variety)
boom is a boom, don't like how you like almost immediately contract your knee, looks weird imo
I don't do much tricking so I don't really know much of the terms, but ill try cuz why not
the raiz(I think) is cool. looks like its gonna be a sick spin thing
