Wait up, let me get a good shot of that ground texture.... there we go. Also, imo, very fluent and epic! 10/10

I made these a while ago and never uploaded them. also it touched frame 12.

putting all my ok ones here because I need to organize.

Make sure you get a single dm on him or something so that he is relaxed.(booms are easier when uke is relaxed, single dms are easier when uke is held)
Another trick you can use is the bruise glitch. Lets say you bruise uke's left pec, and then after that you go for a chest boom. Let's say that the left pec does not dm, go to the frame where you bruise his left pec and then use "SHIFT + P" until you get to a place right before the kick, most of the time that will make the left pec dm. If you didn't understand watch Larfen's video on it: https://www.youtube.com/watch?v=EReFJM6qjJo . Another thing, when you start off going for booms you should go for meaty area's ex. chest and crotch.
Once you are experienced in that then go for more special booms, like core booms. I hope this helped
