The angle isn't optimal, however, watch your torso all through the steps and release. For consistency you'd like less movement (up & down) and less forward lean at the release. Why?
When we bend forward at the waist the down swing can get too steep, causing us to either; 1) lose the ball early off the hand, or 2) use too much muscle trying not to lose the ball early. Too much muscle can lead to directional issues, too.
My advice would be to set your spine angle at setup (a little tilt forward is okay) and then try to maintain that same spine angle all through your footwork and release. It's a relatively easy thing to do that will pay huge dividends as you strive for consistency from shot to shot. Good luck.
