i like 1 and 2, but 3 is too cluttery for my taste. i dislike the overlapping photos, and feel that a cleaner line (all three photos within one rectangle perhaps?) is classier and less hodgepodge looking.
as for web addresses... i think the shorter the better. is annemoore.com taken?
monkeytree.com was taken, and i didn't want to use the word "photography" because it's so long and prone to typos, so i went with
www.monkey-tree.com.
moorethanphotos.com leaves room for misinterpretation on behalf of your potential customers... they might hear it and not understand that "moore" is not "more".
