Let me put aside our rivalry and try to help you:
The boom was cool, it really was. But the execution needed work. The start was stupid, but funny, so that's okay. You didn't grab him, so that's good. But here is the problem, when you connected, your leg went the opposite way of when it was going. You should have contracted your hip, and followed through.
In conclusion, you're not exactly the noob that I thought you were, but you can get better, 8.75/10 on the boom, 7/10 overall.
