The basic premise of this pic is that a mission to Robotropolis goes terribly wrong, with both sonic and sally paying the price. Sally was completely robotized, while sonic fared only a little better by only having his limbs robotized. Despite this, I would imagine that their altered forms would do little to change how they feel about each other, and that's what I tried to convey with this pic, though I'm not sure if I accomplish that.
The background was pretty time consuming and I'm still not quite satisfied with it, I think I might have screwed up on the horizon line a bit.
anyways, hope ya enjoy
