We can not add another column of threads on our front page, and we feel that WIP should have front page space rather than finished work as you need the critique and help to progress through your project. I think most people who critique work on this site would view these forums specifically or through new posts rather than the front page as well so I don't think a finished work thread would not be seen because it didn't get front page space for as long.

However, as you're looking for critique and not to just showcase your work I don't see a problem with posting it in the WIP section if you want, so please feel free to post it up there instead.
