I love the idea here! The word shades is sort of hidden so I wonder about making it lighter gray and eliminate the gradient in the red (makes too many colors). And this is just a personal thing going back to typing class in high school but I've noticed I tend not to favor fonts resembling typewriter fonts.
Thanks for the helpful feedback. The initial font choice was influenced by the 50 shades of grey book cover font. I immediately thought that it could work. Anyway, here are 3 more designs with different takes on the font face, I also made the hand-cuffs a little lighter in gray so that the contrast on the text is easily recognizable.
