Isolations:
Ground zero: Incredible replay. Even though the opener was really really generic, I liked the replay. However, decap could have been easily improved and your arms were too stiff throughout the replay.
Jet set radio: Interesting opener, really loved the flow! The combo was great too. If you work on that, you might actually get something even better. Comeback was alright, but the kick lacked power. You should have pushed the body towards yourself with your arm and then kick it.
I can't cnc grey, since I don't know anything about tricking.
I love your replays, you're really creative and your style is pretty darn good. One thing you need to work on is your dm's. You can gain a lot of momentum but I can see that you're struggling a bit to get booms.
For now, I have no idea. Re-do your application with 3 more equally mindblowing replays, and you'll get my vote.
