Looks real good; like the backdrops! Cautionary note: some of your curves are real close to table edge so consider putting some kind of barrier at each "close spot" to prevent equipment free-fall to floor in case of accidental or intentional (impish) derailments. Some put up wire (or strong thread) fences, some put up plexi-glass. Just make sure it is anchored strong enough to hold your heaviest engine.
