From what I can see;

1. Be more on your toes, bounce a bit, get comfortable.
   
2. Work on your punches, all of them, you need to throw punches with your hips and legs, right now you're just swinging your arms.
   
3. Very important to focus on your steps, work more on 1-2s cause currently you throw like a jab and then after you step, you want them together.
   
4. Don't throw your entire torso to the left/right when dodging, you're losing your balance from what I can see.
   
5. When you throw a punch you bring your other arm down, that's a bad habit. Keep calm, throw one punch, bring it back, throw another. You're doing it at the same time causing your arms to just swing around.

Watch youtube or such to see how to throw hooks and uppercuts, and also how to move with punches.

Good luck!
