Do you know if there is a photographic society in your area? If you want to share your photo's to get some critique, redbubble.com is a good website for digital and flim cameras.
A lot of the photo magazines run websites with forums that achieve similar things. Also as part of the open university course that I took, a similar thing was insisted upon. So you would be set an assignment and post your photos. Then comment on others and they would comment on yours.
The comments were really useful as it would give you ideas and direction to improve your photography, plus viewing how other people approached the same subject really helped.
I'm considering setting up a website to sell photos that me and my mum have taken. I'll let you all know if I do.
