This doesn't look like it should have taken very long, and though I rushed the background, the character line up took a while. I had the family unit as children, so I wanted them as adults.
In my AU, my O.C's Brant (leftY and Nula (right) are twins, conceived and carried at the same time by Amy, stood here with their respective Fathers. Amy, Shadow and Sonic were in a relationship at the time. The comic I'm writing (and will soon get back to) revolves around this time in their lives.
