So they shouldn't express their opinion because the creator might read about it and get their feelers hurt? That's pretty lame.
To me that's all the more reason to say something. How can any artist grow without feedback, good and bad. If X amount of people agree the haircut sucks, maybe it sends a message to the creative team as something to think about down the road.
To be honest, I really enjoy surprise as much as the next guy, but I think it would benefit Sideshow on some of these pieces to maybe let the fans vote on conceptual artwork before any clay is sculpted. Not saying do this for every piece, but once in awhile it would be good to hear what the people buying it think.
My 2 cents.
