I've finally gone ahead and bought my own domain and set up a photography portfolio. Here's the link http://raywise.co.uk . The site is broken down into a few categories and will show my style of photography across these ranges. Users can add comments without logging in and add links to their own sites or others.
I have to say thanks to my many Flickr friends who have given me the encouragement to pursue this idea. Their comments have given me belief in myself to go forward and take a chance in the professional world. Thanks also to Getty Images for giving me the chance to share my work in their database - some of which have been licensed already.
Have a look at the new site - please let me know what you think of the design and any problems you might find.. cheers.
