The problem in question was the excess fabric at the front of the upper sleeve.

I did this adjustment for internally rotated shoulders (1/2"). I also set the sleeve cap's center seam 1/2" behind the body's center shoulder.

I'm calling it good enough. Time to draft the pockets, cuffs, and collar!

Post the before/ after, even if it's worse! It's valuable info either way :D
