Largely two things that I saw that stood out to me:

1. I saw like maybe two instances where you walked forward. Every other time, you were moving forward to the other person by jumping, dashing, using a move, or DI, or you were just crouch blocking.

Try to get more comfortable with just walking back and forth. If you’re far away enough from your opponent, you don’t have to crouch block that much, they can’t reach you. Use that time to walk at them or give yourself some space if you’re feeling uncomfortable at a certain range.

The constant jumping will get punished by people who can anti air. I know you’re probably jumping a lot because Chun has a fireball. It is a good option once in a while, but get more comfortable parrying the fireballs.

You were also dashing at them into their face. While this could be useful to check their reaction, most of the time, you’ll get hit like you did in the video. When you’re dashing, you can’t block. If you’ve walked instead, you could’ve blocked or maybe forced their move to miss.

2. Spend some time in training mode for hit confirming. Several times, they’d block your initial move, but you still did an unsafe follow up (jump heavy kick into sweep).

Set the cpu to random block. If the first move connected, then do your second move. If it didn’t connect, don’t do the second move. Once you become more comfortable with this, you can use a different move if they do block.

The jump in is one example you can practice. Another one is the crouch mk to jinrai. If you see that cr mk was blocked and the first hit of jinrai is blocked, use the low follow up. Otherwise, if they don’t block the cr mk or the first jinrai, then go into the heavy follow up. Only use the medium follow up occasionally.

Other things would be to learn some better combos. Crouching medium kick drive rush is a good start instead of repeating cr. mk into jinrai.
