How in the hell have I not seen this thread before?!? Great idea, clean artwork, and well implemented. I really like how you did the player buttons on each side, reversing the buttons and their outer rings. That is a really cool detail.
If I had one suggestion, it would be on the marquee. The rest of your art is so sweet, but that just doesn't look as good as the rest of the cab to me. I would do something in the same design vein as your control panel with buildings or something, darkened enough to where they don't distract, and a big ol spy vs spy logo. Maybe slap an "Acade" below it or something. I think that would do your control panel justice and keep the theme going throughout the cab. Something similar in your FE would be sweet as well.
My 2 cents. Kick ass work!
