I hit a 2hbh so beware of my advice, but I agree with what I've read above.
You're opening your shoulders up too much before contact. You're not getting the racquet head below the ball at all. The combination of these two things means that you're kind of slinging the racquet through the ball. Your grip might want to be more Eastern - hard to say.
On other thing, keep your head still and your eyes on the contact point until after you've completed the stroke. Don't immediately pull your head around to follow the ball from the racquet - it doesn't change the flight of the ball, but likely messes with your stroke because you've probably started to move your head before contact.
You're initial set-up looks OK and the basic hitting structure of your arm and shoulder look OK (no bent leading elbow).
