I think this is overall a very decent video of how to pull of a Thai leg kick. A minor quibble though, in the second half of the video when the girl is working with the hand pads, she is moving her hands excessively. This is a habit that needs to be corrected if you ever have competition in mind, as it telegraphs to your opponent your intentions before striking.

Some people would also nitpick about both the pros and cons of rotating the lead leg as well as torquing the cross hand down with each kick, but that's more of a stylistic preference as you're trading power for defense.
