I feel bad about not knowing who Wander is. Judging from this description, he's a character from Shadow Of The Colossus. I have at least heard of that. I just loved all the little details in this. There seem to be different styles clashing together in this one. I like the symbol on his chest.
Of course, these aren't your characters. It's weird how I mistook them for yours at first. Wander is probably the best looking part. His goofy design contrasts so well with the skinny robot. He really is quite skinny.
