Start1 - really nice opener, I liked the first kick, however you could've gotten the groin separated quite easily.
The second kick had power but it lacked flow. Instead of going for the path which will give you a big amount of speed, plan ahead and figure out how to get maximum damage while mantaining your flow.
I don't recommend bashing uke's body parts against the floor to dismember them. It doesn't look good. What I would've done is let go of uke's chest and kicked him torso into the ground. That way it looks more realistic, looks better and gives you more options to continue from there in my experience.
Indeed7 edit- The opener got you a really nice amount of speed, but you kind of wasted it. Rather then aiming for a surer outside hit, aim to clusters of joints like the chest or groin. I managed to turn it into a 5dm boom with 5 minutes of tweaking.
Again as with your other replay, after the nice beginning it went downhill. The second kick didn't look as powerful.
I liked the pose, but not so much the transition.
What I'd recommend is toying around with different joint combinations. Even if something looks like it won't add any power, I find on occasion that just relaxing a knee, or raising an arm can change a 3dm boom into a 4dm boom, sometimes even 5.
You've got lots of potential, keep practicing and working on keeping your flow and planning your moves ahead of time. You know what I mean, rather then going for an automatic kick, try building up some speed and momentum.
