I hadn't even noticed that there was dithering. I find this way much more interesting than the regular kind you see in most tutorials. I like that I can actually see the shapes for each shade, I think that's what I don't get when I tried to go for pixels back in the day.
I don't have much to say except that, like everyone else, I love this thing. The idea and the hearts all over it combined with the pinkish and purple hues just makes it an instant favourite. I also like how even though it's stylised, you can still see the real shapes of a skull in it, as if the bones had real texture.
