Love #15 even though I didn't think I'd want anything with hearts, but it's done in a tastful and simple way. I'm not sure about the others. If it were just a photography business I think I'd like them more as it looked like a camera shutter closing kindof, but it's going to be more than photo so I'm not sure about those.
Thanks for the update. I do like the city in the heart, but I think it would be really hard to tell what it is unless it's viewed very large, which for the most part it won't be. Thanks!
