When you baited Rachel's 2C, you could've punished with something more damaging, such as 3C FC > 2B > 2CC > IAD combo or 5C CH > 6CC. Against that weird astral setup (the 1st time), you could've air dashed past her to get away. Also, the 236A didn't connect in your 236C CH combo because 236C has bad proration. After a 236C CH you're better off following up with 5A > 5BB > 5CC > 22B.
Your blocking is good. I wish I were as patient as you. At 5:25 when you knocked Rachel away, I would've opted to chase after her rather than acquring stock. You don't want Rachel making it harder for you to get in.
Those moments pain me so much. I know the feeling well enough, though I feel you should've brust when Rachel caught you with the crossup the 2nd time. I also feel you could optimse your combos. For example, You could've done 5A > 5BB > 5CC > 623C > j.214D > 6CC > Stuff once you had Rachel in the corner rather than burning 2 stocks for around 2.5k. I don't think you're making the most out of your oki options too. It's like you'll wait or dash a little then wait. There are a lot of options you have to make the opponent scared of how and when they tech (high/low mixup, throw, 3CC etc). You don't make the most of it and then the opponent easily gets back into attacking you again.
I think you should try frame trapping that player too. He seems to like pressing buttons in your pressure.
Be careful with rolling back in the corner too. It's not very hard for Rachel to reset you there, especially with George there.
