That is sooo wrong. Very funny though. The composition seems to be lacking. maybe place the cow closer and slightly behind the burgermaking it appear as if the cow was eating on the burger. Then use a verticle composition and get in a little closer.
I guess this meets the challenge. After all you couldn't get thoses patties from that cow! However this picture just doesn't do anything for me. Maybe if you lost the french fries with the toothpicks in them. They are my least favorite thing in your shot.
