I've been accumulating ACEO cards and boards steadily over the last few months, but I didn't have the nerve to actually take the plunge and try painting one of them until I picked up some nice gouache colours in Minnesota. I still need to practice a lot with these new paints, since it was tricky to get the opacity I wanted, but I think these turned out quite nicely for a first try!

Colossus was painted on a metallic silver card, while Nightcrawler was painted on a simple black card.

Media Used: Gouache on illustration board (ACEO)
Time Taken: A little under 2 hours each, give or take.
