Those drywall guys really jumped all over that job! Can you imagine what a video would look like from the moment the crew piled out of the van until they rolled away? Must have been like a Chinese Fire Drill inside your garage! lol
As others have said, you've got a great design and well-executed!
Just a crazy 'suggestion' -
It seems it is common knowledge that OSB ***** paint and swallows light even then, so how about using that crown moulding as a 'wire chase' for wrap-around low voltage halogen spots/floods? If you went with 6"-8" face on the angle mounted moulding, and 4" for the flat mounted moulding (in the corner), the entire mould run should appear about the same height to an observer on the main floor. Using the wider moulding around the shop area would allow you to use either swivel surface-mount fixtures or recessed puck-style halogens for wall wash lighting or maybe even task lighting below.
It's definitely an additional expense up front, but being able to change the light source from straight FL's really changes the look of any space. Seeing the various shops on the thread 'http://www.garagejournal.com/forum/showthread.php?t=70650&highlight=night' really illustrates how various light sources impact the overall 'look' of the garage.
