You look like a pretty young dude and it’s great you have a passion for lifting.
First thing if you want better form checks in future you need some better vids of your lifts. Talking like useful angles e.g. directly from the side and lighting/quality
Deadlift
Hips shooting up a bit at the start. Wastes energy pre much and can cause you to lose tightness. This guy recently had a similar issue and it’s all in his thread:
Squat
Squat is a bit of a clusterfuck with your pelvis doing all sorts of weird things and your hips shooting up and good morning that shit which ends up turning into a sticking point. I’m gonna recommend you go off and fine tune your squat from start to finish, breaking up the lift into set up, walk out, descent and ascent. When you’re a bit more solid overall then you can post up a formcheck to refine your technique. Right now there’s more to be fixed than not so it’s pointless.
Here’s some vids to get you started. Don’t try to learn and apply it all at once cos you’ll get overwhelmed.
