Really love the CP, Zangief side, and most of the marquee. Stylistically I think the detailed image of the woman on the bomb looks out of place against the bold posterized look of the rest of the art... that's actually the same issue I have with the Godzilla side, on it's own it looks great but stylistically it just looks different than the rest of the cab. I saw that you were going to vectorize the Godzilla side, so if you can reduce the detail while keeping it clean and bold like the Zangief side I think it will look great.
Either way, love the direction you're going with this!
