working the bob is what is creating alot of your bad habits , get on a heavy bag .
your too hyper , probably because you are posting a video sherdog and trying too hard (understandable), slow it down and get the mechanics of the punches down pat , then speed it up a bit . when working on combinations , mind the non punching hand position ,
your kicks are not proper , i think that you are trying to regain your balance using the kick through method when in alot of cases it was not necessary ,
start off with throwing a round kick and concentrate on striking and landing in a balanced fighting stance , sometimes you kick through if you miss but if you dont miss the kicking leg has to retract back to your fighting stance , the same thing with your switch kick (strike and get back into fighting stance )
your back kick and spin hook attempt are lacking practice , indeed there is only one way to develop those kicks (lots of practice) but the fundamentals are not there ,
the spin back kick really doesnt have a spin on it , the trick is to turn both your heels at your target / turn your head and torso and push out in a lineal fashion , driving with the heel striking and retracting , ,, spin hook kick is totally diiferent motion
i wont even get into the driving of the elbow or termination of torso rotation , which at this stage is too advanced for you , just work on the fundamentals.

the above techniques have a tkd flavor to them , the muay thai version of the round kick has a step pivot as opposed to the pivot ,and some other small differences , i chose kwon kicker because he demonstartes alot of the other body mechanics that are going on within the kick
