the first one isn't a madman, uke stays too intact. otherwise it was better than the second one, though, because it had some strikes and not just you using yourself as an uke-grater.
the second one was too slow, and you stopped for a few times, which kills the flow. although fluidity isn't a must in madmans, I think a flow to the movements, a.k.a. keeping about the same pace throughout and such, is very important.
if you wanna, you can see what I consider a madman in that link in my sig.
