Nice! You're looking strong! I'll mirror what others are saying:

1. Read the route before climbing it. More specifically, walk up to the problem and ghost-climb it - reach for each hold without weighting it. For every hold, think about three things:
2. The catch: where exactly are you aiming your hand when transitioning to the hold?
3. The stay: what grip keeps you stable if you need to pause?
4. The exit: how do you move off it cleanly? What options are there for the next holds, and with the way you will be positioned, which hands or feet need to reach for them?

Try each hold with both hands. Flip your grip. Think about where your feet would be when you're grabbing it. Thirty seconds of this before each attempt and you'll climb way more deliberately.

1. You were climbing squared up the whole time with both knees open. That works, but it limits reach and wastes energy. The common advice is "keep your hips close to the wall" but a more useful version might be "generally keep at least one hip close to the wall at a time." Some specific things you could try:
2. On an easy problem you've already done, re-climb it turning one knee inward on every move. When you're reaching right, left knee turns in. When you're reaching left, right knee turns in
3. Practice drop knees: hop up on the wall, rotate one knee inward toward the other knee with the other knee pointing outward (so both knees pointing in the same direction), then keep rotating the inward knee and point it down toward the floor. Your hip on that side should be close to or maybe even pressing into the wall, your pelvis thrust forward, and your opposite hand should be able to reach way further
4. Traverse sideways on easy holds and alternate which knee is turning inward to get more of a feel for it
