Majority of the time, they would say something along the lines of " No, I've lurked at pixelation before, I'm afraid those guys are a little too advanced for me, or may be too harsh on my work.").
I personally fail to see how this is a bad thing? Eatpoo was in its glory days a good example of a forum where people actually would benefit being part of it (well to be honest, they were at times a bit TOO rude, which I don't think is an issue here. Here people would actually help you even more, by making paintovers and such.). I think if you want to be an artist but you're not willing to learn, or willing to accept that people will have opinions about your work every time you bring them to public, then maybe it's for the best that you make your art only for your mom or store it in a drawer. I don't think it's elitist to say that if someone can't take criticism, they should stay away, I think it's just true. If this place would change into an asspat community, everyone would suffer. If you just want praise about your work, there are places for that too, but I don't see it's here.
By no means the critique should be rude or otherwise degrading, just the opposite but even as hard as it is, you should be able to recieve criticism if you want to learn. I don't think Pixelation is a show gallery either. I think this applies also to the issues that Xelados has. Since some people have traditional training, of course they will bring out those points in their criticism, and I don't see why they shouldn't? One might even gain something if they would listen to those advices, no matter how personal and "unique" style they have.
These are of course only my personal opinions about what Pixelation is and isn't so...
