I'd like to see them in mov format. That way I can step through them frame by frame in Quicktime. Can you send one side and one back to: email@example.com?
I'm with hoseman18 about the back foot coming up early. Related to this is how your back leg/knee never really fully rotates under as much as it could. My suggestion is to focus on really rotating it all back there, along with good, aggressive hip rotation. The back foot must turn over and will drag on its own after all of this rotation.
The landing on the closed side of the target line, I believe, is related to not rotating the hips into landing enough. Because of this, I think your hips are depositing the front foot too soon.
You are rotating, I think, your hips and shoulders roughly simultaneously. Get the hips rotating prior to landing while the throwing arm is still on its way up toward high cocked.
Send the files though. It really helps to stop frame them.
