The overhead
There are four characteristics that Are important in the overhead.
One is preparation, two is footwork, three control, and four is watching the contact point.
This is like watching a professional baseball player miss a fly ball, it’s commonly done. the challenges of getting your body aligned underneath the overhead in order to strike it is the number one challenge. I think players do by pointing with their non-dominant hand to track the ball into the racket; so that would be my suggestion on the overhead use your left hand as a guide to get under the ball before you strike.
