Your beginning run started off a bit odd, and it looked strange how both your feet left the ground. (You should always have atleast one foot on the ground at all times during a run) It also looked strange due to keeping your pecs extended most of the run.
The first punch was nice, but I disliked how you scraped him. I think if you had thrown the punch over him, it would've looked much better.
The kick didn't flow in too well, and it caused you to go off balance. A set up for another punch would look nicer.
You went into a set up to launch forward, but it didn't look so good. It leaned a bit too much which caused it to look awkwardly positioned.
The next kick flowed in nicely, but a tad bit too slow.
Everything right after was off-balanced, and you stopped/slowed down your flow a couple of times.
The pose was decent.
Try to smooth out the way you execute your hits.
Stay on your feet a lot more. The help of your lumbar and glutes should fix your balance.
