Right quickly, as I have to go out and pick up a computer I brought on here.
1) Gmail email address, as others have said. Not great.
2) Both mobile and email address are tiny. Why should customers have to work hard to contact you?
3) Images arn't great quality. Not your fault, but you are selling photographic services. If your images look crap it reflects awfully on you!
4) Website is disjointed. The rolling images on the homepage just look like random pics you have taken. You need to be more specific. imo.
5) About me - sorry this is terrible. Not being a dick, but you don't come across as proffesional. Im not having a dig. Just trying to give honest feedback.
6) Portraits. So so sorry to say this. But I can't see one attractive person there... I know thats horrible but if I was a young girl I wouldnt want to look like any of them.
7) Landscapes look good. This is what you appear to have a tallent with. You arn't showing this off with your site.
8) "other projects" - if this is a site to make you money, then get rid of this. Customers do not want to be part of a project. They want a pro to offer a service. If you were massively established you might get away with this.
9) I don't get the "raven photography" bit. It's just my opinion but I'd think you were a bird photographer.
Sorry I can't spend longer ripping your site to bits. I know I come across as a prick saying all that, but it's honest. Your landscaped are good. Focus on what you do best.
ALSO - copy this guys site
http://boycalledben.co.uk/ or at least have a look at it. It's clear, well laid out and is enjoyable to look at. It draws you in and makes you want to have a look around.
