I saw your Neopets work - it's amazing!
I've been doing Neopets work now, too - I've slipped away from the MLP:FiM community and have entered the Neopets community.
Some of my work utilizes pixels, and nothing else. Some of my pixel-work only utilizes four colors or less per sprite. (That type of color is the same type that was used in the 1980's, back when color graphics cards were limited in what all colors that they could produce. How I know that, I don't know - I wasn't around at the time.)
