You only asked if you needed more powerful hits... If you wanted proper cnc DON'T ask for something else in your post.
But alright:
The first part up to the first kick was pretty nicely done, it did well to lead up to a good replay. However the hits were terribly weak, could have been aimed better, and the replay was too grabby. I also don't like it when uke is so asymetrically dismembered, it looks a bit ugly at the end.
Overall if you want a good replay then remake it from the first kick ( including that one)
