what was first me putting two images next to each other to compare them turned into this collage. I'd had the stencil-sketch idea around but until now had no reason to put it on anything. Mostly old images in my gallery, but the 2 black and white ones were done by friends  rubilin and another friend who I'm not sure if they're on FA or not.
It's kinda cheap, yes, but it did get me practice for composition and the like.
