ok, i'm hoping these were online cuz you seemed pretty sloppy.
you're CGs were slow to begin with and you suck at approaching. in the first vid the only kills you got were from an edge hog and when she gimped herself.... also, you were blizzarding way too far away and hardly using any nair. plus, if you have them at the edge at 70% its pretty safe to just edge spike -> edge hog.
i haven't watched the other vids yet, but from what i saw work on approaching, spacing, cg speed, aerials, tilts, timing.... man i am just being a ****.....
