faces made out of random swirly things? hasn't this been done?

This is cool. It might look better without the light green box shape though. You need the light green back there but not in a box, it seems to "trap" the great organic shapes that you have going in there. Maybe use that darker green shape as the outer border for the light green fill?

to me, this looks a lot like a previous threadless tee

cool! yes there was another threadless submission with faces made out of swirly things, but the idea has been done before that~ :)

feminine/bulbous doesn't mix

just lose the box and I'll buy it

The green box is over powering.
