OK, let me first admit that when it comes to artistic creativity, I'm at a loss.
I have already converted my non-working Captain America cab to a MAME cab (though I still need to get the AVGA card working, but that's for a different board).
I need help in creating a Super Mario-themed cab. I know I can find some artwork online, but I need help in coming up with a cool "look". Even just a starting point.
I was thinking of calling my cab "Super Mario-cade" or something like this. I want to create a marquee, side art, and CP overlay. I prefer the look of Mario from the Super Mario 64 games over the other looks (much more cheerful and colorful than the original SMB). I thought the name "Super Mario-cade" created using the letters from the Super Mario 64 game would look good.
I'd appreciate any idea, tips, or even the fully-developed artwork

Here's an older pic of my cab if it will help:
