Charmander and Squirtle were made in first half of 2012. Bulbasaur was made today. I remember that Charmander was the first one - painted at grandma's house, Squirtle the second - painted at university and in a bus, and Bulbasaur the last - painted in buses, at university and home.
I plan to do more compilations of 3DS paintings.
