I think it looks really solid, just a nice clean forehand. I really wouldn't bother about with worrying about finishes at this stage in the game, as long as you are comfortable hitting that forehand during a match it should be good to go.
The biggest thing is more active feet. I know you are on a ball machine and the ball should
bounce to near the same spot every time, but the ball machine is a great way to practice setting up your footwork on the fly. Not really a critique, but it's always good to practice footwork when possible!
