Side art dilemma

[Timstuff]

As some of you may remember, I did a vector version of Solid Snake from the original Metal Gear a while back, and originally I was planning on printing it up and having it on my cab medallion style, but as I got to thinking more about it, I was wondering if perhaps I should go a little further and make full side art for my cab. It will most certainly end up costing me more, and take more work, but it may look a bit more impressive, and look less like a conversion (which the cab will not be). And I still haven't figured out what to do for the left side of the cab yet.

So, any advice as to what I should do? What kind of backdrop image and/or character collage do you think would be good to build around this image? And, is it even worth the extra time, effort, and money it would take, or should I stick with my original plan to do it medallion style?
