when you label something WIP, to me that's asking people to point out all the flaws. I happen to be brutally honest at times, when asked my opinion I once told my good friend that her new hairdo "looked like something from the play-doh barbershop" before I even thought to try and be kind. (in my defense it DID look that way) basically if you don't want to hear anything bad about your work then don't post it. It's that simple.
