I love Tron Legacy
especially the soundtrack by Daft Punk -- both of which were inspiration for this drawing. I havent thought of names for the characters yet but I think the smaller one is rookie stage, and the evolution is champion level.
Random fact -- the rookie level digimon has hologram ears.
The background is a modified wallpaper that I found on Google Images, so I take no credit for its creation.
The specific tracks that I listed to while creating this were "Derezzed" and "End of line".
