If I had to list one critique about the site, it's that there's never enough biscuits available when somebody starts a new build and we all 'join in' to follow it... some folks are taking way to many and not leaving any for the other folk.
On another note though,
The 'rules' seem perfectly fine, they're just guidance not a dictatorship, just how this forum has always been...
There's a good bunch of folk here, and to be honest I've never seen any comments 'tearing' somebody's work apart when they ask for 'critique', unlike many other forums. Folk here are quick to help out, and that's what makes this place successful.
I for one always accept critique on my builds, each build is nothing more than another learning curve and although I might have been modelling for a fair few years, I'm no way an expert at it, sometimes a different set of eyes spots the things that you haven't seen and a bit of guidance from everybody else helps makes the difference between a successful build and one that your not happy with.
