Thanks for posting the videos pepto. I have a couple of questions/tips:
1) Were you allowed to use straight(linear) kicks? If so, the front kick particularly can be useful as a scoring technique to the body, and as a means of stopping your opponent from jumping in. It is also very easy to follow up with punches, unlike the side-kick.
2)You moved forward very well and did some good combinations. However when moving backwards you were much less effective. Again, you could use front kicks to help this, but you could also use more tidy footwork to feint coming forwards again while moving backwards, this will put him off balance for a moment, allowing you to withdraw to sparring distance again.
3) The techniques you did use were generally very sharp. Well done!
4) In the first fight, the ref stopped the fight from carrying on at a couple of points. Was that because your opponent was cowering?
Anyway, nice one!
