Looks really nice, I like the way the characters seem to belong, the way they interact with the wording or look like they are standing on the grid.
Also... Congratulations on having a wife who appreciates this hobby enough to design the marquee with you, consider yourself lucky, most of us are happy enough to have our wives tolerate our cabinets, some have wives who empower us by pointing out cabs or parts, and the luckiest have wives who play and build with us. ( I think I'm somewhere between the first two.)
On the other hand some people may argue that the luckiest of us don't have any of the above. I however know I would rather have a tolerant wife than none at all.
