My screen (1280 x 800) means you have to scroll down a little to see whole of images on home page.
Logo could do with a little work, look at the spacing between text lines on Freedom Light and then the photography by Darren O'Brien it just does not look balanced, maybe also play with the text kerning to align Photography by and Darren O'Brien
Gallery page just looks a little cluttered, some with description, some without and first travel photo looks like a landscape to me which has 0 photos, just confusing.
Contact page text blends together to me. Use of colour or Bold on headings e.g. Phone would help make this clearer to the eye. Also why email link and contact form on same page? In fact 3 pages have contact forms, which is a bit OTT. Maybe a contact me for more info on each page with a mail to link on the text would work better?
Personal thing, but I do not like links pages is main headings, maybe in footer would be better, remember every one they click takes them away from you!
Personally I don't get the different site for weddings? Maybe a page that becomes the wedding page, links to separate galleries etc. might make more sense.
Lastly more images in each section or reduce the amount of gallery types. Build up a portfolio of images on one of your subjects, then when you have a decent amount (10 or more?) set up a gallery. You prob working on putting more in, but that is how I see it.
As always constructive criticism, nothing personal (hopefully people always take my website crit this way) I am harsh and may seem picky, but then again so is the average client.
