It was a rainy day, I do not like rain, because this made my hand wet and cannot find the correct hand feeling easily.
I want to keep my elbow and the right shoulder in the same height, took the right shoulder as forward as I can, but must keep comfortable. The pure soft hand type always made your elbow too low, so keep the elbow and the shoulder in a horizon is really difficult.
After this, I still need to make my right forearm and upper arm in a small angle. Just as Steph's angle:
At the sideview, the ball almost hit forehead, the right hand just close to your right eye, almost in that height.
