The funny thing is that the image in your mockup looks like a gray piece of !@#$% with dingleberries attached to it somehow, with a hook sticking out of it for some unknown reason, and like it has stink lines coming out the back it of it that are somehow blue like the chemicals in an airplane toilet.
Anyway, in all seriousness, the first image in your mockup seems dumb, but the single color scheme in the second one is easier to handle.
