I agree with IndigoSplash, the absence of comments can be disturbing. The absence of visits, too. I always wondered why some artists did get hundreds of visits in the first hours of their posts, and some others not, while i do not really see much difference in both's work quality... Well maybe it's the question of being known or not ;) Having constructive critics can be interesting, even for amateurs who don't pretend to be artists, just like me ;)
