since the technique of clone stamping has been around the block, i think this tag would benefit from color, perhaps coloring all the individual faces differently, to create a mosaic
Thats a step in the right direction, but overall it seems the faces are oversaturated...if you want to post the psd i could show you what i had in mind
It's a neat effect and I really love the texture you have built up there, but I think you need to take it further. Add more stuff in! I think some brushed graffiti looking things would work well with this one.
