My only problem is just what someone said in one of the first comments of v.1, it looks just a little to photoshoppy. It looks like all you did was use a couple of filters then used some fancy brushes and submitted it. I like the idea but the execution dosen't quite lend itself to a finished shirt.
the main photo looks like a photoshop filter was put over it and resulted in the sketchy lines. the monkeys are lost and so is the concept. mother nurture is a clever name and i was expecting an image that is more clever.
i think, keep the concept and rework the image and the possibilities of what the image could be. remember clever is loved on threadless. sells a lot of shirts, and you have a clever root.
keep at it, but this image isn't working.
please go ahead a tear mine apart with a critique at http://www.threadless.com/critique/29307/Love_Machine
It shouldn't be that obvious. Or If it's realy what your going for, than It Needs something extra
