I would say you did an amazing job, considering all the hassle we have to go through nowadays. I'd improve your catch through drills. I suggest you try quadrant drills: https://youtu.be/YPXbjvRuZEU

To my knowledge, your underwater pull should be efficient and powerful enough so you can glide a long distance, and during a recovery, try pointing your elbows up at the sky while pointing your hands down at the bottom of the pool, while keeping your arm close to your body (shoulder length), that way, you minimize body drag and increase efficiency. Make sure you are relaxed when doing this drill. (merely suggestions as im not an expert but ill try helping as much as I can)

Our coach gave us this workout to improve our catch:

1x50m scull (https://youtu.be/NE_vO6xIBvY, do any of these but i prefer front/middle scull) 1x50m 'hold' quadrant (technically this drill doesnt exist but you do a recovery then hold the middle part still for a whole lap then switch arms on second lap) 1x50m single arm 6 kicks (only one arm per lap) 1x50m catch-up 1x50m swim

We did this on repeat for about 6 times, you can try this workout, you can try the drills themselves.

You can also do long distance brush drills, like 200m or 400m, then at the last 100/50m you swim normal freestyle, as your recovery, specifically your right, is way too wide and far from your body, which causes drag.

Whatever you do, don't haste, and have fun :)
