I want to put this on a t-shirt
I know how to stencil, I am just wondering if it is dumb to try to do something with so many colors, and if too many colors are not a valid idea, then what sort of color scheme will I do?
In addition, I think it would only be pertinent to have goreshit - dancefloor degrader on it somewhere, I may have to think of some ways to do that.

Help me out bros.

There's only 3 colours + black that you'd need to use. If you're any good at masking you should be fine.
Get a buddy who can airbrush to do the goreshit part, and possibly even the lines if you don't want to have to make some hellishly fine cuts.
