the talk about pixel art for me ends when what you've made is put on a surface which is rendered in 3d. A polygon on something. When the pixels are stretched, skewed and so on, it's over. Of course this doesn't mean anything, discussion can go on, the process can be scrutinized, whatever. I'm just saying that's where the benefits of pixel art stop applying for the art, when you mess with the atom of the universe (the size and shape of the singluar pixel)
