An ACEO is a 2.5" X 3.5" drawing, the size of a regular trading card.
"Card" on the left was meant to be an ACEO for a charity commission, but I upgraded it to a larger piece to (hopefully) compensate for the inexcusably long time that it took me to finish. The two cards on the right are actually "double" ACEOs, composed of two cards each!
Left: Jin for *Hirui
Top Right: Tsuki for =Lunakia
Bottom Right: Merka (and catfish) for ~Ghost-Fish
Mediums: Coloured ink, graphite pencil, and ballpoint pen
