Definitely an inspiring thread, found ex post facto (for me). I borrowed thematic elements from someone (pictures found somewhere else, and RaceDeck's FB site "I think"). Didn't look further into the source of the shots, until now, but examining this thread well there you go.
You did the heavy lifting, starting from a rougher template than mine, page 1 of the thread through current. I merely polished what was already in place, in my case. I think you've maximized limited space well.
(Chuckle): I get a kick out of my Yamaha shop stool, bought on eBay from a dealership for some nominal price. Maybe you need one, could be a good addition!
