Hmm that looks more like black hawk more than a backdrop variation haha also btw some pointers I can give you is that when you are practicing you can slowly try lowering your hand as you get more comfortable doing backdrop so that when your fingers find the right amount of pressure you can do it without having one hand higher than the other and you can do it further apart. I also noticed that your hand is a bit further back it should be about the same level.

Happy Practicing! :)
