Nice site and its very clear what area of photography you specialise in. I have a few comments though
1) The homepage - I like the image you have chosen as it has the 'cute' factor and sets the tone for the rest of your site and what your all about etc. However, I think I'd remove the text below. As Steve pointed out in his post, its not the most cheerful start to a website, and maybe a separate page for it would be better. I'd also have some kind of flash animation/slideshow of your images to make make your homepage stand out a bit more.
2) Photoshoot Prices & Print Prices - when I clicked on the photoshoot prices I was expecting to see just that; photoshoot prices. Instead you have listed the prices for your various print sizes, which can also be found on your Print Prices page. Although you do state that prices are tailored to individual needs and to contact you for further info, I think it kind of gets lost by the Prints info just below. I think you could combine both pages into one and separate them by using a title or something?
3) Formatting - I'm using IE7 on my work PC and when the pages load they are all a little off-centre meaning that I have to scroll to the right to see all of tthe last tab, plus your name and the ends of you sentences etc. Except for your homepage, all the other pages have huge expanses of empty black space under the content.
I hope you find these comments useful...I am not a website expert by any stretch of the imagination!
