All that detail you describe would not be good for a shirt. Maybe a poster or a web image, but not something you'd be able to easily mass produce. When printing media like on a shirt, at least when screen printing, you try to keep the colors to a minimum, one, two, maybe four if your printing guy/gal is really good, and that's like the maximum. It's not good for a whole gradient or a large range of color, like what you're describing for the road being dusty and going off into the distance. It might make a nice looking reverse-printable home-made t shirt, until you wash it the first time.
The helmet on its side on the front of a solid colored t shirt (dark brown) would go a long way. Maybe put the C on the back. Assume your "audience" is at least as smart as you, they can figure out what it's for. And if they can't they'll ask, that's what a good shirt's for, right?
I dunno what a good shirt's for actually (as opposed to a bad shirt
).
But I do know design principles as they apply to printing. I did this pretty quick to show what I'm talking about, so the hat isn't futuristic, it's just kinda traced from the Toriyama picture. But it gets the point across.
Incidentally, I put the words on the back too, they felt really corny on the front. Under the C, it makes more sense. So the front is like the teaser/question and the back is the answer.
I'll do different colors if you want.
