thanks Mr Pumpkin
I was trying to go for something like a Dominic Thiem's backhand and that is why I'm rotating my torso and my back shoulder goes to the front. Not sure if I'm doing it correctly, nor if I should be copying Thiem. However it seems a more intuitive backhand to me.
Dominic Thiem would explain the exaggerated takeback. DT often needs to stand pretty far behind the baseline to implement this. He may fare better on slow clay than on a faster surface. However, he did win the USO title. I didn't see it but I suspect that his prep might have been more conservative for that surface.
Your racquet drop is really good, you get your racquet low for good topspin. Your contact is out in front and you rotate your shoulders. Keep your head forward and not to the side so that you can watch the ball. Your chin should touch or almost touch your right shoulder.
thanks mr ball machine
is coiling rotating my torso as if I were trying to show a number in the back of my shirt to my opponent?
Yes. Exactly. If your forward swing is mostly arm, you are, for lack of a better term “screwed.” You are pulling the racquet toward contact. You want to get the back muscles involved.
In this video, you went with the opposite extreme with your head movement. Instead of too much movement you have almost none at all. Eyes / head forward for your UT / preparation and as you start your drop. As the racket continues to drop, your head should be turning as if you are tracking the ball getting closer to you. During your forward swing, your eyes should go to your expected contact point -- slightly forward (toward the net) of your front foot. Now, keep your head still through your contact phase. Don't look up until you are well into the follow-thru phase.
The swing is not already good. There are a lot of these kinds of posts in this forum. A person comes here looking for advice on how to improve something, people give advice and then someone comes on here and shoots down the advice with nothing more effective than “don’t listen to these phony 5.0s” or “you are good enough to get two balls in a row in and beat a 3.0.” This isn’t a support group “hi my name is Daniel and I have a suspect backhand.”
What you should learn is the proper mechanics. But you shouldn't be trying to copy someone else's style. There's a lot of scope for freedom of expression within a stroke without compromising mechanics.
Hope it was clear 
Just use the second to last paragraph as that's what you should know and will improve your whole game, good luck!thanks so much!
No. I think Shroud was talking about the side of the racquet that hits the ball facing up to the sky, meaning the actual stringbed, not the frame or edge of the racquet.
With Roger and Stan, you only see an open racket face when they are using a continental grip and are hitting a backhand slice. Don't see it when they are hitting the topspin BhAm I the only one who doesnt like the hitting side of the stringbed pointing to the sky on takeback? Dont most players do this with the strings pointing to the side and not the sky:
Thiem's takeback isn't that loopy either. He's got a straight arm takeback that makes the takeback look a lot larger than it actually is. OP's original takeback had his hitting hand go well above his left shoulder at the top of the takeback loop.
The best way is the time tested way. Video can be an aid but it is no substitute for attending a tennis tournament live. If you watch good players live in real you can 'feel' how to hit the ball.
What if Jesus never picked up a racket?
I recall watching a rear view video of DT hitting backhands on clay a year or two ago. He was standing quite far behind the baseline and his preparation was rather large (seemingly somewhat excessive). He may have changed this a bit in the past couple years but I believe his loop is still (often) rather large
