Axisweb.org has been supporting artists since 1991. They showcase the best UK contemporary art and craft, and connect visitors with the people who make and present it.
Artists can set up their own portfolios here after going through a curated selection process and paying an annual fee. This part isn't open to students as you need to demonstrate your professional engagement in the field after graduating. Because of this 'selection' there is an extremely high level of artists and work across a wide range of media and styles.
The site offers features, advice, reviews, rants and opportunities in the field.
An all round excellent source for the professional artist.
