You need to manage more the distance between you and the opponent. Not being too far or too close. It is a really important point in what i seen in your replays. When you do a jump, try to land on your feet. I know jumping everywhere is a kind of entertaining but most of jumps that you done in these replays are useless (because the bad direction/distance). Be more fluid with your moves, when you start a move, try to relax/hold more your joints.
Keep up your good job ;)
