Oh, fuck them. That's so ridiculous. Who can say how much effort was spent but the artist? And if I spent a week stacking paperclips, would that be art just because I spent time on it? I find people like that ridiculous -- if you have so much time and opinion on your hands, why not spend it making the art that you think is better, instead of putting down other people's effort? Sorry for the rant, it really annoys me when people are unnecessarily negative.I think your textures are very emotionally powerful, and visually beautiful; it's clear you put a lot of love and effort into them. If that doesn't make something art, what does?You keep doing you.
