Not sure about the control panel and marquee yet, but something like this for the sideart
I was expecting something more round for the top of the cabinet.
Here's an idea: make the cabinet the same shape as the "superlaser" control in the game.
As for the side art, if you don't want to show the spaceship in a fight with enemies, it's at least missing planets and stuff in the background. Do you have access to the artwork? Maybe you could ask the authors.
For the marquee, I would use the space background with stars and planets and orbits with the simple text logo and integrate the "Asteroid Base" logo somewhere into the marquee, using commercial marquees as templates.
You should check the trailer again, the spaceship is not pink-only like on your side art, maybe it was pink-only a few months ago in the game?
