Below are 3 more variations on my original, influenced by some work by Ian Wright and feedback.
Top Left: Original
Top Right: Slightly eroded face, massively enlarged. I enlarged it because this was suggested, I think it adds the element of wonder, because it does make it less clear but, at the same time, you can still figure it out- and when you do it seems pointless.
Bottom Left: This is the original just slightly unformed. This made the dynamic element to the image, makes it seem not yet formed.
Bottom Right: I liked the feeling of wonder from the first and the dynamicity of the second. So in this one I removed more blocks of colour to create an even more unformed image.
I like this last one. It really catches the idea of the blocks and (i think) makes for a create visual piece.
