I feel like I might have made this blog roll sound to formal and scary to get more people to post and comment, more. I really like what's gone up so far!
Please by all means don't be afraid to post something that is half finished or that you don't like. Getting feedback early on your work is sort of the whole point of starting a forum like this. So don't hold back, drowned us in art! I post the challenges to give people ideas but you are by no means limited to just posting work that is responding to a challenge.
