wayne, it is looking great. very nice attention to detail.
did you consider switching the orientation on the rocker switches for the lockers?
to me, it is more intuitive to push the rocker towards the light to make it illuminate (and hence, lock). Small, small difference, but I think better.
Also- putting "engage" down the left side of the plate will make that side less cluttered, graphically, than disengage. there is already more text on the left than the right, so putting disengage on the right will balance it more.
just a thought.
