I'm no expert, but here is some advice from what I've seen:
Work on your blocking; maybe try some stuff out in practice if you're having problems blocking specific character's setups. For example, a lot of Naoto's will go straight from double fangs into low shots so knowing to switch to a crouching block right after you block her double fangs will keep you from getting caught by that all the time.
Know your matchups. Don't use j.C against an airborn Liz, her j.B will always stuff it. Find out when you can punish stuff, I saw you miss a bunch of punish opportunities that might have won you the match against that Liz.
Don't forget your 5b, it's a wonderful punch and if you manage to get a FC off of it you can do a ton of damage. I keep seeing you use 5a, and even worst, 2a but no 5b's getting thrown.
Upon landing a 5a you just went into the autocombo, learn some better combos off of 5a if you're going to keep using it so much. If you're falling into the 5aaa part of the combo because you're mashing a (used to happen to me a lot at first) you can prevent the autocombo from happening by doing 4a instead of 5a.
Use your dashes, airdash, and 236C/D to approach and position yourself better.
Don't play passive against Chie, sure she needs to get in your face to do damage, but so do you. and you'd much rather be setting the pace than letting her do it.
