What Lvl are these Overheads and what do I need to improve

i think you better to improve your volee because is bad and its a fundamental shot, you should aim to get points from this, not from overhead

The level looks like low intermediate. You don't look set when you're hitting most of them, you body is still moving backwards or you're jumping and you're not ready for the shot. Move into position faster and get your racket up, prepared and frozen faster. If you can't, let it bounce. None of your shots are going into the corner as well. Your bandeja should go into the corner most of the time because it gives your opponent a double glass rebound to deal with, and give you more time to get back to the net. It also gives you more margin on your shots. I also don't know if its the angle but some of these lobs look like they were going out. You're also hitting higher risk shots while your opponents are stood at the back. If they were better at blocking they'd catch you out of position often. Go back to basics, focus on moving back fast and preparing early, then freezing your body ready for the shot. If the lob is fast or you're not set, let it bounce. It would be a good idea to have a coach check your technique, even if you just did 1 session.

I'll go against the grain again and say I kinda like your overheads. They're not technically great but if you develop a decent smash you can have a good rulo/gancho/smash/tontona combination all from the same preparation and impact point. It's not the most orthodox development path for an intermediate player but if it interests you it can be very effective. What you're missing the most is the threat of the smash to pull the other players out of position. That's my playstyle and it's pretty goddamn good. Very rarely do I hit a bandeja or vibora.

Heyy OP, need your help. I can't comment on the overhead, as I am a beginner. But I have also bought an action camera to record myself. I am unable to set/mount correct for best angles Your angle is perfect, can you share your setup?

You need to be travelling forward in the Over Head. Basically before hitting, you should plant your weight on your right foot and push forward through the motion. That way not only does your OH get more accurate but it prepares you for what is coming next. If you don’t have time to do this, then you were too late and you are better off letting the ball go to bounce and back glass, and you can lob back instead. You are extremely vulnerable when flying backwards the way you do in the video. By the way, regarding vibora you need to do something completely different to what you’re doing :) I think you need to have a coach for that or look at some videos at least because it is a bit too much to explain. Also a Bandeja needs to be more to the (right) side of your body. Actually the last OH in the video is a fine bandeja, and it is also the only one where you somewhat travel forward. It is for sure the best OH in the video. Most of the OH you do looks mostly like a gancho - which is a good OH type by the way and a great first OH to learn. The gancho is more above the head, and it’s purpose is to keep control over the net, like the bandeja. It is mostly used when the ball travel above you. In the video, there is a ball where you could have played a bandeja, instead of moving away from the ball, you move in under it, making it a gancho. For the balls that fly above you towards the left, the gancho is the right choice if shot (except that you’re flying backwards on basically all of them 😆) Finally, a lot of these OHs you should just have let go, but if you want to get better behind the ball for me to stop saying this, you should work on how you travel back. It is good that you are rotating your body quite okay and try to run sideways, but you still seem to be late on almost all the balls. Probably you need to anticipate better when a lob is coming. When your opponents get an easy ball that they can lob on, already then start to get ready to back up. Or maybe these lobs were meant to let go. Remember there is nothing wrong with accepting that your opponents did a too good lob and let it go. You can always show them that you can lob good too :)

I think you could hit your overheads more in front of you (still to the right) 

Your over heads are good Well controlled and in the right regions

All of the shots are cross court. I would like to se more to the middle and maybe some to the player on the forehand side of your opponents. Only cross court overheads will be really easy to read after a while.

Great placements on overheads

Other question, what LeBron Viper are you using? And how do you like it? Thanks already!

Not bad, but consider that the level of the opponents is really low. A higher-level player will pick off those at the net. And, in that case, you must have a solution with more speed. Also use more the middle to move the opponent.
