New Web Sites

I now have 3 satellite web sites supporting my main site at www.sally-jane.com One purely for pet portraiture which is http://www.petportraitsbysally-jane.co.uk/index.html, one purely for pet cards here www.petportraitsbysallyjane.co.uk and one for other forms of photography including human portraiture and still life images here www.sally-jane.co.uk
As the new sites were purpose built rather than simply evolved like my main site, I am hoping they will be easier for viewers to navigate. The main web site needs some work to tidy it up as it has turned into a sprawling mass of pages but I don't want to lose any inbound links so weeding out the rubbish won't be easy. Any tip would be welcome.
