sometimes: the first hit was ok, it's good that you're managing t get power behind your hits but it looks awkward and holdy. Try to relax some more joints. Then the 2nd hit wasn't great. Often in replays, holding the same grab for multiple hits doesn't work, try and only use grab when it's essential. Then the actual decap kick was extended waaaaay too early, you get a lot less power behind your hits if it's swinging through the air fully extended, keep it contracted or relaxed until the point where you can extend it to hit the sweet spot. Then at the end the dancing thingy looked a bit holdy too.
Also you could try and edit another kick in at the end, your hand falls on top of the body, it could be a good opportunity to practice booming.
