You have to understand the perspective of our curation. We look at PLENTY of posts everyday. I understand what you think because I also appreciate artists who don't offer any coloured-commentary for the sake of the rawness of their art. I'm an artist too. But please understand we're merely advising on what you can do.
Plus we have no way of knowing authenticity other than work process being expressed / articulated. What will people think if we're always voting on just a simple pic in a post? We wouldn't want to be a guild that blindly gives away votes on something that's thoroughly gameable. Maybe a step-by-step or progression of the art coming into life is a good way to show it.
That's not to accuse you of anything at all, but try to put yourself in our shoes.
And this is just one guild, it's also up to others to do their voting.
I hope this sheds some light into what we do, we're not just lemmings voting on stuff blindly. And notice there's no contract or obligations in any of these at all.
