Your other entries are pretty, but they look too cute... we are trying to get away from "cute". See if there is something more 3D that can be done with that idea.
We love your entry #3... it has our initials and looks like a camera from the "top". Any way you can work some variation of it? Try to stay away from the hearts... I already have a heart logo and my husband is the one that doesn't want to use it anymore... so I don't think we will end up picking a logo that has a heart, unless it can look really manly :-) Thanks!
