For those that get a chance to browse from work... Flickr is often blocked (as it is at my place of employment), so all I can say is:
Lovely BLANK homepage, with the rest being lovely and full of blank spots. If I were in it for the business side of things, I'd take steps to make sure just about anyone could view what you wanted 'em to see.
For the places where I could find pics, I agree with the comments above. They all seemed like small snapshots, and nothing really led me to think "pro". My first impression was that it was a place to share casual pics with family/friends... nothing to make me stop and sign up for a session.
Again, just my .02. If you're happy with it, and you have a steady business flow, that's really all that matters, right?
