We like what you're doing here! Could you try a few variations for us?
#1 we need the tag line incorporated at the bottom of the logo big enough to read. #2 something is not quite right with the hearts. maybe loose the outside line and just keep the two hearts. also maybe try them smaller. #3 I'd like to see the "ART" in a little font that's a just a LITTLE more feminine.
I'd love to see a variation on #1 with word ART in a slightly different font and with a single magnet and a single heart on either side of the text where the impression is that the magnet is pulling the heart toward it.
