Requesting someone clean up the rest of the jpeg artifacts on this, or whatever you can find. It was already run through Waifu2x, but there's still a lot left. They're kind of throughout the image, but you can see them clearly in Rei's hair, the edges of Asuka's underwear and the background.
Pre-Waifu2x for comparison (this one is also darker and has dirt):
