I am certainly not the best in these mods at all, but from watching these replays, what stands out to me it how you contract your grabbed arm when going for those kicks.
It's more apparent in the first replay than the second, but I feel if you keep that elbow extended/held, then that arm DM in the first reply wouldn't have happened, and you would have a more powerful kick. It would also held a little with controlling your opponent in pulling him into the kick.
Let me know if this helped or you need more explanation. I'll continue to look at those replays to see what else I can give tips on.
