Hello there.
Up until recently, I worked at Prima Games, where I organized the layout of the Pokedex section for the Sun and Moon guidebook. Therefore, I had access to information about new Pokemon. I snagged a list before I left, and remember what most of them look like. The best I can do for designs is draw crude recreations. Feel free to ask any questions.
