ok, well, I'm guessing you're wanting feedback on these... so here ya go.
1. I like this quite a bit... though the lighting seems a bit harsh on the belly, and doesn't seem to be there enough on the face. At least, that's my opinion
2. not really a huge fan of selective coloring, and definitely not a fan of it here. Also, in the bottom right of the photo it seems there is something like a bow there, which I find distracting.
3. again, not a fan of selective coloring, but hey, whatever. I like the stroller thing, not a bad shot at all, would probably like it more in just B&W though.
4. I like the shot, and the idea of the shot. However, I think it would look better without all of the extra footprints going around the outside of the heart. Also, the baby looks a little hot to me.
5. I kinda like this one, though the angled horizon bugs me.
