Artist Alley help/advice please?

Okay, I have two styles I'm playing with for buttons and stickers for Artist Alley. I don't know which people would like more though. Any thought/opinions on which I should go with would be very appreciated. ♥

obviously these would be cleaned up and coloured for buttons, but you get the point~
