Hey man! Thanks for being the first person to put something forward! Firstly your colour grading is great! The exposure is very nice, did you use a video light? What I’d improve: - 45 seconds is a long clip, there’s a lot of sections where the leather jacket isn’t in frame fully or out of focus. I’d cut those parts out. You can then use a transition to merge them back together to make a sequence. - Once trimmed into shorter clips, try stabilise them. There’s only so much we can do in post but will smooth out the bumps and shakes. Following on from this for next time try and be as stable as possible in the water! - Remove the audio (unless you like it), if add in some calming music from YouTube’s Free Music library which will help set the scene - The cropping. Not sure if Skools made it like that but it looks like a 16:9 landscape video, exported as a portrait video then played as a 16:9 again. I’d edit it first on a master timeline in landscape, once you have it graded, the clips set you can duplicate the timeline but this time set it to portrait. Then zoom the clips in so they fill the frame, you might need to do some key framing so the subject stays in frame. But all in all, you’ve got a great clip, the colours are great, the subject is close to its sharp. You’ve got great separation from the background.

Resolve its its own beast to tame! If you try and do everything all at once it becomes very overwhelming, just take it one step at a time and you'll get there! I'm the same! I can't decide wether or not to do photos or videos on a dive!
