I don’t think I’d wear that Mr. Do! design if you made it into a shirt. I think it is the stark color choices that were made for that Mr. Do! artwork (which you didn’t do obviously) with the red and the yellow.

I would almost like to see that as just white on a dark grey with maybe the Do! text in red….or maybe do some sort of weathered, textured, faded look so the colors aren’t quite so in your face. That boldness may have been in touch with arcade presentation back in the day, but I think that is different than something you wear around in public.
