I'll comment on the madman, since I suck at tricking, and realism.
It was pretty nice, I liked it until you turned upside down, and started to kick what you could, I think it gives the replay a some kind of random look, where you don't know what you are doing. Also the way how you got into the final pose should have been more dynamic, that raised arm looks pretty much stiff, and looks like you held all there, I would relax all the joints above, and next to the chest if I were you.
I also edited the replay, where I stayed on my feet, and just posed right after the boom, I can post it if you are intrested.
