"Can you give me some tips to improve my squat?"
Sure. Of course I can. The Squat Rx videos are full of tips. I put up tips here all the time. But, here's the thing:
Tips make you better, but tips don't make you good.
A tip might open a door or two, or clear some clutter from the path, but you still have to go through the door and the road still needs to be walked.
If you want to be good at squatting, you're going to have to squat... a lot. To understand the difference between squatting one plate a side and 5 plates a side, you going to have to add some plates. To understand why everyone recommends squatting for weight gain, you might have to try a few high rep sets... and eat A LOT. To really understand squatting, you might have to experience some very long plateaus. Along the way, you might have to learn how to overcome an injury or two...
If you want to get good at anything, you have to put in the time and effort. There is no way around it. Now, you might be talented and gifted, and you might be pretty good to begin with. But, to be really, really good, to master it (whatever 'it' is), will require years of practice and study.
