Never seen, used, or smelt a stink bomb so no personal reference here. The colors are interesting and it's certainly very abstract. Within the context of a scent/aroma challenge I could envision a scent coming from this. I dont see any areas where you could improve on it.
I know I should probably know what this is but I can't identify it. Is this supposed to be mold? Barf? Without knowing what it is it is hard for me to say if it is really stinky.
