Males have two distinct sex chromosomes (XY).
CHROMOSOME living ... but DEAD rule Everything.

CLEVER.
im taking biology right now, so i got a kick out of it. ha.

smart

Clever!

Bravo. $5

Great unusual take on the sex and death theme. That the whole diagram forms a skull is the icing on the cake. Good thinking, really nice design. $5

clever

Interesting. May have too much going on with the lines. They take away from the clean boxes and shapes. Perhaps if the lines weren't dotted?

Those babies have huge heads! Nice work and good colors.

depressing :P but awesome :)

Didn't judge, because I didn't get it:/

Clever! The design looks a bit too busy though.

Great design. But a word of warning, be careful of the placement of large circles on the chest. I don't know many women who would want to draw attention that directly to their breasts (the Nice Boobies shirt, is, of course, a clever exception). 4 from me.

Czarna made a good point about circle placement. Could you make a slightly different design for women that would intentionally place the circles closer to the collar so that you don't get the "LOOK AT MY BOOBS!" effect?

maybe mix up the life paths some? The two canes and the wheelchair are all pretty much the same idea (old age). I'd like to see more of a subtle hint that people start off being very similar, but through life, become very different, but that in the end, they're all dead. As it currently stands, the message seems to be "Everyone starts off the same, pretty much stays the same, and then they die." Which is kind of a pessimistic ending to a shirt that starts optimistically.

yes, the circles on the chest would keep me from buying this, love the concept though!

i would pay $5 for this! if you follow my meaning.

funny though, if you move the big "dots" up then the nipples become "xx"s. Can't win for losing.

Love the concept, love the execution.

The concept is very interesting. I like the implied movement of the shirt.

Thanks for all comments.. and all advice.
I agree with you all.
Thanks :)
