I like the neon sign a lot. Classic. If I were to make one suggestion it would be to install some feature brick. Would look awesome over the rack backing the neon. Could be a fucker to keep clean though if you get roofspace dirt comg down or in chalky areas so maybe just up high or strategically placed.
I really like the look of feature brick paving too, with old, distressed brick. I don't mean some faggoty uniform herringbone lay, I mean like an actual design that suits the shape of the room. Could be really nice for the entry/desk area. Again, you'd need to consider cleanability, I guess.
You could be a reall asshole too and supply tinted chalk and call it Brick Dust.

Just make sure it washes out.
Btw, I think that bricks, although strong in compression are fairly weak, um, tensile-wise. That's why bricklayers can just bust them with a whack of the edge of a laying trowel. If you cut one thin enough with a brick saw you could just snap it by hand. So you could have cut pieces and hold a monthly contest to see who can snap the thickest piece of brick and then give 'em a Champion Brickbreaker spot on the wall for the month.
Wish I owned a gym to do this stuff in.
