@uknsaunders just a few thoughts
Good on ya for putting up a video
I'm jealous you're in the nets already
There is a lot to like
What follows is food for right, not criticism and entirely subjective based on one type of bowling for 9 mins only, and one viewing only.
1. In the set up and the back swing your hands do seem to drift away from your body which would create that out-to-in-to-out downward swing; I would look to bowl 5th/ outside off-stump line. I reckon you love in swing and straighter balls, and less so away swing.
You do look stronger on the legs (especially as timing improved as the session went on); tho' there were good cover drives, almost square drives.
2. Timing improves but there is a hint of foot planting. (I couldn't hear any sound on this clip but I'm guessing it was a bowling machine given the bola balls and the fairly consistent length). If you watch it you can see yourself the consequences of planting (loss of power and direction, etc). This could just be because of netting with a bowling machine.
3. Is it the camera angle or do you have an open stance? I think this helps your leg side shots, but that in conjunction with drifting hands and foot planting leaves you reaching for the off drives. That said there are a couple of really cracking looking drives through covers.
4. You mention over balancing, and a few times you are squared up after driving balls pitched on middle , middle-and-off, and on the off side; and a few times those same pitched balls end up going to the leg side too, even when playing a cover drive. Again I think this is a consequence those things already mentioned above, but also playing sometimes in front of a braced left knee and strong bottom hand coming through which tucks your elbow in at or just before impact.
Your best shots are those where you are waiting longer, when you are decisively forward or back and when your leading shoulder points in the direction you're intending on hitting.
I hope this is of interest.
