most of the important stuff is already said by kid, especially her remark about the kick, keeping the leg lose and just not drive through (during a sparring match that is) is important.
some minor remarks if i may: gameplay: it's okay to sometimes just push someone backwards if he comes to close.
just with both hands a snappy push, perhaps followed by a nice roundhouse.
stay nice and loose and be just a bit more lighter on your feet.
edit: oh and i forgot to say it already looks pretty decent, im sure you'll get there. ;-)
i'd recommend besides the sparring also some padwork with an experienced guy: works two ways: he can really go through the details of footwork and he actually knows how to do padwork.
Good job, it was more fluent this time but you still tense up, relax.
