Your right leg goes forward at contact. You are off balance. The proper look is a ballet kick with the right leg going back to balance the body going forward and up.
The leg will stop the hip rotation when you are square for a first serve which translates to (if the rest of the form is correct) an increase in racket head speed. The whip from ground up.
