Well, this render was... interesting to make X3 As you can see I fiddled with it, experimented with it on GIMP, seeing if I could make it look more realistic... but I guess I fail xD Anyways, time for me to explain
This is where Nevada was banished. I suppose her father sent her off into the woods and then just abandoned her there. He returned and told Nevada's mommy that she was too late. I'm not quite sure who the other horse is, but I designed her as Tucson's mother. :3 She too, feels the loss of her son's playmate.
Ohh man, GIMP is awesome xD
