Here is an idea, it's fairly self explanatory. Is there anything I can do to enhance it?
I think the colours work and as far as I can see these are the best represented monsters/villains. I haven't added the many godzilla or king kong films on the key because it'd take up the whole shirt.
Also, I can't think of a good title so if anybody has any better suggestions that'd be great. Monster Scale? Rubbish!
