I saw your new account in another thread before reading this one; I was pretty confused for a while. On another note, I've seen your avatar somewhere before. Was it Eternal Sunshine of the Spotless Mind? That was a really good movie.
Anyway. I took another look at your videos. Good matches. I'd tone down on dthrow to vinewhip a little - its easily avoided through DI or an airdodge, and it made your grab game predictable at times. Plus you left yourself open a fair bit whilst trying to land multiple grabs. I also agree with Retro on the use of nair. Tone it down and throw in a few more lag-cancelled fairs. Bair walls are fun as well.
Oh and when you edgehog, try hugging or speed hugging rather than jumping onto the edge. It's just faster, and cuts out the chance of their recovery hitting you.
Good stuff though. Very nice.
