These are just my initial opinions, I have several web pages and I am not the best designer myself !!
The home page has no colour, it is a photography site black and white is not right!
I would have the home page as a home page with maybe a nice pic of someone in your studio with lots of colour.
Prices etc should really be on a page off the home page.
Galleries are woefully slow but you know this already.
Clicking on "relationships" brings up three images in boxes over a larger image, the three pictures in boxes are blurred (if this is by design it is a strange decision for a photographer)
Just noticed families does something similar - really you want your best images on here and nothing blurred.
If the blurring has occurred due to re-sizing then re-size with something else, if it is due to the gallery software then again use something else.
