Is my backswing correct for hitting?

[greyguy]

Thank you for your explanation,
I agree with your assessment of "slinging"

I just read on another site about takeaway for hitters. It stated that one way to view it, is to clap your hands together and then look at what happens to your right forearm when you hands come apart. It has a slow and slight turn or rotation.
I think this what you are saying.
