Telling me your TKD doesn't tell me a whole lot. The only thing I assume when I see someone say they are TKD is they like to kick.
There's all sorts of different levels of training in different TKD schools...though I'm sure you already know that.
From what I've seen of your sparring on stuff you have posted here, if I were your coach I would concentrate on a few things, depending on how much time you have to train. First would be keeping your hands up at all times, even when kicking. Next would be keeping you hips under your torso. I noticed on your two on one match that when you saw an opening you were so anxious to get to it that you sometimes lunged to get the strike in. This will have the side effect of leading with your jaw and reducing the power of both your kicks and particularly your punches. Leading with your jaw is just asking for a knockout. Your going to want power in your techniques to either knock out your opponent or make him tired so his gaurd slips and his offense isn't as good. Stamina, stamina, and stamina. Anytime you take on a ring fighter of any sort you are going to want stamina. When you get tired your reactions slow and your hands drop. Obviously both of these you want to avoid.
The last thing I would say to work on is counter striking techniques. If you are good at counter-striking you don't always have to chase your opponent to score points. This will eleminate some of the problems with lunging and will conserve your energy.
Good luck woth your match. Hope some of this helps.
