Your blockstrings are really weak. I see you sometimes ending with just 5C, which is -9 on block. Try not to go into 5C so much on block because its pretty bad but if you do, go into either gunshot or 2AB xx gunshot. Gunshot is a good blockstring ender but don't forget about SB gunshot. You're sitting on a lot of meter throughout some of these matches where you could be using it to extend/start pressure or extending combos with 2AB xx 214AB on a crouching opponent. SB gunshot is +13 on block so you pretty much get to do whatever afterwards if they block it.
I saw you did stuff 5C(2) 236BB xx heat riser 2C a couple times and pulled them out of the corner. Probably not a good idea because doing anything after the second hit of 5C does really bad damage and isn't worth the meter. If you don't hit confirm into heat riser properly and get 5C(2) you'll have to settle for a 236AA ender. Just don't give your opponent a free ride out of the corner unless it kills.
You've already mentioned too much jumping as an issue but youre specifically relying on jumping backwards and doing j2D or double jumping and doing j2D way too much. Its good to keep those options in mind but once people start to figure this matchup out, they're going to punish you hard for it. Lastly, if you get 2D/J2D blocked you have enough time to dash up and confirm into a fatal counter combo or start your pressure. If they press a button to break your persona, it might cost you a card but you get a counterhit if you're fast enough.
Your use of 5C in neutral is really good. You cant get much off it but its great for controlling space. Hope this helps.
