I love it I got that they were faces/heads. Not necesarily dolls, but faces. I agree with giving the pink one a face. I'm either way on the message. I agree with making the website addy less obtrusive, yet still noticable enough... you might need to do a few tests on paper to find out how big/small your font propotions should be. No point in "wasting" a good bag (and it wouldn't really be wasting, as such as you want to make alot of them, corect?. And if there were alot then you would want each one to be unique as well, to go along with your stand out message)
ANyway I dig it, its cute!
