Very last swing looks good. But like Erik said, you need a FO pic to determine some of the important things like backswing sway, and it appears you're dipping your head just before the transition which can be indicative of improper weight transfer.
Still early extending and swing is a little disconnected regarding the upper and lower body. Try to feel like your upper body hangs and waits on the lower body to initiate it. The swing is one chain of events and your upper body initiating its own separate movement will throw off the end result. But definitely a lot better than the first swing vid.
Personally id prioritize coordinating the hips leading and upper body following before I did anything else.
