Nice layout, I hate when electricians just space lights out based on the overall space don't don't take into account the inner structures and use of of the various spaces. If it were me, I would outlets for future lights be place in the two unaddressed corners (Upper and Lower Left in the drawing) so that should I want to add additional lighting in the future I could just hang them and not have to call in an electrician. Even just the conduit would make expanding the lighting easier down the road.
I also would break the lighting plan into at least two (three would be better) zones. That would reduce the load on any single circuit for future expansion and if I don't need the entire shop lit up at the time I could just turn on the lights where I needed them
Some of the things I have been thinking about for my future shop, God willing.
