Tell me, are you a member of JPG.com? I joined last year but only recently started getting more involved with it. It might be a good idea for you if you are serious about your photography, wanting feedback and wanting to stay motivated. They have a lot of themes that you can "enter" your pictures in. Plus, you can find a lot of inspiration as there are so many great photographers - I could spend all day on this website (although, I'm still not sure how it all works). I especially like that you can subscribe to an RSS feed of your favorite photographers so that you will always know when they add a new picture.
My profile is here if you are a member or end up joining
