Not a bad looking swing, man. I'm also trying to dial in the right amount of hip turn and torque on my swing, I went from shooting in the low 100's (can't tell you how many times I've shot a 101) to shooting in the low 90's and even high 80's a couple of times. Keep in mind, I'm still very much an amateur golfer. But two things I see right off the bat are:
* More hips. Your swing looks to be alot of arms and not enough hips. Turn more in your backswing. I recently read that you want to try and point your back to the target. I haven't tried this on the range yet, but I would imagine stepping back from the ball and taking a few very slow backswings will tell you how far you can turn comfortably. A buddy of mine helped me alot with this analogy: Pretend your standing in a barrel as you go into your backswing. You don't want to sway side-to-side in an unconscious effort to generate power. It's there. You just have to tap into it.
* Push your body through after making contact with your right foot. It should completely turn and point at the target, along with your hips. Right heel up after impact, pushing with your toes. But remember the 'barrel' analogy... you don't want to propel your body forward and create a sway. You're simply aiding your hips in turning towards the target.
You seem to be keeping your left arm fairly straight, which is excellent. Left arm straight (I've heard a slight natural bend is ok), and push the club away from your body with your right hand. This has greatly improved my accuracy.
Last but not least, clubs make a HUGE difference. I've played with crap clubs until a few months ago. They can only take you so far. I'm not sure what's in your bag, I'm just throwing that out there.
These tips have worked wonders for me. If anyone sees any bad information, please correct me, because I'm currently utilizing these tips as well.
