Your left foot is fine - shows your weight is transfering properly. But your right foot should not be off the ground the way it is. I suspect you're actually starting your downswing, or left transfer, by raising the right heel. Try to keep it on the ground. At impact, your right foot should still be essentially grounded, rolling to the left (a bit like your left foot in the picture), with the heel maybe very slightly off the ground at this point.

I know raising the rigth heel, as in your picture, can feel powerful and you can hit shots flush - but not all the time. I believe you actually leak power most of the time by raising the heel like that. Also, you're likely to be losing balance as the right foot will throw the right hip. You need a lot of compensations to hit the ball well all of the time if you do that.

It may take a bit of practice to keep the right foot grounded more. Try it slowly and see if you notice the difference, particularly through the ball.
