These are looking solid, my dude! The only thing I would suggest to try is using your pivot foot to help pull you back a little faster so your base isn’t so exposed after you kick! Next thing to do: put two kicking techniques together! Teep into a kick, kick into a teep, rear kick into a shuffle and shuffle kick into a rear roundhouse!

Let me look into this and write something up! You are correct in uppercuts and downward elbows, but knees are not a concern on a hanging bag. There are unique bag shapes like the Fairtex bowing pin bag which has a couple different curves to it that offers multiple angles/striking surfaces to train most techniques. https://www.nakmuaywholesale.com/product/fairtex-hb10-bowling-bag/?gad_source=1&gad_campaignid=21339079808&gclid=CjwKCAjwnZfPBhAGEiwAzg-VzLRD8NzZIqb1S2d0-ljLwE4il3Nr8SNzbEMRyVmAGLDQ5Z6p8XuMPRoCSsIQAvD_BwE

Hell yeah, my dude! And your timing with the bag is amazing! For your switch kick, you should try throwing the rear roundhouse in south paw to really understand hip swing and the start to play with where your hip can be as you shuffle!

Rear leg is looking solid! Good turnover and body alignment. The check is looking a little tight. You want to think of your shin as a wall when checking and not try to pull your heel into your butt. You want your ankle under or slightly in front of your knee to create a solid shield. In regards to the lead shuffle, your shoulder slightly pulls back while the hip goes forward but i think this is because your kick is going around the bad as opposed to more towards the front. You want to picture hitting more towards the front of the bag and less of the side. You’re well on your way to having a solid kick on both sides!
