This started out as an experiment because I've never used halftones before but I was quite happy with the result.

I think it has a positive message aswell!

i dunno.. it's too much happiness in there. Made me smile, but what would make me smile more would be if the guy was pictured as already quite sucked out, greenish, collapsed in a chair ;) And the drop with the hose still smiling like it is.

I haven't had great experiences giving blood, so I find this shirt pretty creepy... especially the hose still attached to his arm.

LOL! Dass funnie. I think you should add a little more detail, but that's really cool. And nice job on the halftones, btw! Nice. Cold Shoulder FRIGGIN' critique...
