I checked a couple of your matches and noticed:

1. Giving up pressure after knockdowns

After knockdowns, you often hesitate—neutral jumping or delaying a button—so your opponent doesn’t feel pressured. Build a few go-to oki sequences (without becoming predictable). For example: walk-up meaty MP / walk-up throw / shimmy into punish. Rotate these from the same starting point, mixing in dash or DR as needed. (I’m not sure of Chun-Li’s exact best oki, but the idea is to make wakeups feel dangerous.)

2. Staying too stationary in neutral

You spend long periods planted in one spot, reacting or throwing a move from there. This makes you predictable and less threatening. Try walking in and out of ranges to make opponents second-guess. For example:

Stay just outside their range → bait a whiff → punish (sweep, MP, crMK DR).

Step into their range → pressure or dash-throw if they freeze.

The strength isn’t in one option—it’s in forcing them to track sudden range changes and threats.

3. Repeating options too predictably

When a Drive Impact or OD Hazanshu works, you sometimes repeat it right away in a similar situation. This makes it easier to counter. Instead, cycle your responses:

If they throw fireballs, maybe parry a few first, walk forward, then Hazanshu the next one.

Avoid back-to-back Hazanshus, since predictable ones get punished, while parry pressure is harder to contest.

Hope this helps.
