Using instagib doesn't make it look better. The people in this community don't like instagib replays because the dismemberment is some kind of achievement for a nice hit.
Also it would have been smarter to post both replays in one thread instead of opening a new one.
My advice would be to focus on using more joints while attacking. Use your torso to put power into your kicks and time your shoulder movement correctly instead of just extending your hip and contracting your knee.

don't use instagib,it makes you look bad.
and also there's a rule on smileys,3's the limit,sorry for backseat moderating,
but as nuthug said,try to use all your joints when attacking,it can make the move alot more powerful.
