Critiquing Headless idiot:
You did an interesting opener, looks a bit like an aikido snap kick but then you turned it into a sortof bicycle kick, it would of been semi decent if you extended the right knee and got a decap, but instead you got a pec dm, with your knee. Which looked pretty bad to be honest. Should of aimed it better and maybe instead of contracting both pecs, extended one and kept your arms more relaxed.
The rest of it are just generic dms, no hits or anything so nothing to comment on, but they are rather unexciting. Try to do a few hits or doing an all out madman.
The headthrow was also unnecessary and there is no pose.
Streetfight:
Too many hits and points delivered before the first dm. Semi-Unique ideas. If the remainder of uke that you pushed to the ground made his chest dm, it would of been cooler, again the head throw/grab looks messy and unnecessary. The whole thing was a bit stiff and lacked a certain flow and momentum, but the scramble over uke was kinda cool and if you got a few more dm's in and some clean hits it could of been pretty cool.
So as requested, there is your C and C.
Hope this helps.
