Is it just me?
I'm sitting here scratching my head trying to see the difference in those two sketches and for the life of me, other than some unrelated pencil lines in the background, I can't.
I'm just having a hard time seeing the relationship between the concept and the pencil lines.
Also, just a note...if this is a work shop you may want to reconsider your ceiling height of only 7 ft. Light fixtures will hang down even lower.
On a positive note you will likely have the most interesting shop in the neighborhood. Can't wait to see your progress as you start cutting joinery.
