Sweet stuff. But the last one could have gotten more dismemberments. Sambo madman had a nice flow but a bit meh in the end. It looked like you were stomping to stop a fire or somethng. Random madman was nice too. It was a bit fluid IMO. The manip was bad, sorry but a grabby manip aint good. It looks wierd. Rawr im angry was pretty neat but not as good as the other ones. It has a nice Tempo near the ned though.
As an overall rate, 8/10. Its pretty good. I've seen much improvement for you and I see potential in you. I'm sure with some more practise, you can become a great replay maker. No shit. Just try to get as many DMs as possible. If you're making a decap, try to dismember arms or knees while you're on your way. If you're making a split, try to make a corehit. If you're making a madman, find whatever way to impregnate uke and try to get as many dismemberments as possible. Dont afraid it. Believe me it gets even better. I wish to see more of you later ;)
Good luck! And I hope it helped.
Tempo out.
