your pre-impact position looks great to me.
Your noggin is back in good position, your right leg
has kicked in nicely, your left leg is starting to bow
out towards the target. Also you right shoulder has
droped nicely and your left shoulder is comming up,
indicating that your are coming from the inside.
I like how you have stayed down and not come up
out of your posture- something i have trouble with,
Now my unprofessinal opinon- your left hand grip looks
weak, and your left foot is toed out more than
i like. ( But what do i know?)
You appear to have lost most of your wrist cock
but that close to impact, how much should you have?
I am no expert , but a stronger left hand grip
might help bow the left wrist at impact and retain
the wrist angle a little longer.
With your left foot toed out it's hard to tell
where you are playing the ball in your stance.
If you play the ball too far forward i think you can run
out of wrist cock before you get to the ball, but thats just a guess.
Your left hip appeares to have bumped laterally a bit much
and maybe should have turned more at this point in your swing,
though it's hard to tell, but your shoulders are diffinetly
more closed than your hips.
Herbert can you do a posed picture in the position
you want to be in and post it and lets see
the difference? Your picture looks good, and a lot
of us would like to look that good at pre-impact.
