Looking much better! Shadow kicking is a little awkward, but that's reasonable.
Your kick on the bag is looking a lot better, but can you wait until it's fully swinging towards you before you kick it, at the moment from the camera angle it looks like it's just ended its swing to the left, when you kick it with your right leg, if you can wait until it's nearly in front of you before your leg hits it you'll feel a better impact. It'll also subconsciously train you to cut off your opponent with kicks. You might actually be doing that but its a bit hard to tell from the angle
The only other thing I would say, but this is ME thing, not a universal thing, is to also practise an extended arm on the kick.
My coach is a Thai of a similar age to Surat (he's a bit younger) + he taught me to do that usually, but swing down for extra power. So if you're dealing with someone who likes to punch, having your glove in their face during the kick will muffle them, and also allow you to post and frame off them after a kick!
That way you have some coverage for both a power kick + a safer round kick
Happy to help!
