Serve needs to be more fluid. I believe that it's best never to stop the little forward motion. Before you toss the ball, you point your back toe. Put your body weight actually on that foot and then push off onto your front foot as you're tossing the ball. Right before you hit, all your momentum will be going slightly forward and you should have both feet together, pushing off both toes and rotating. Your stroke and placement are good. Just work on using your whole body into the shot.
