This is kinda weird. Your first few are, frankly, terrible, but the skill suddenly jumps upwards. However, the skill of the last one does NOT match up to the good ones. Also, in the second last one, the otherwise great replay was broken by that horrible slow knee, followed by a stiff pose.
I'm sorry to say this, but i am suspicious. All replays are made with Toribash 3.8, which implies that they're all made within the last 4 weeks. Even if the first one is made 4 weeks ago, and the last few today, i highly doubt that anyone could become so skilled in such a short timeframe. I'd like an explanation to this, and i'd like to have my suspicion proved wrong as well.
