Nice - the first one is probably my favorite and I agree the "expression" on the bear's face is hilarious and certainly makes the photo.
Out of curiosity, what were these shot with and is the color the result of film stock, a preset such as VSCO or you freewheeling it in post? I find the color palette especially appealing on the first two, and I'm usually a "technicolor" type of guy. It gives these a slightly menacing or melancholy vibe, in my opinion. I like it.
As I stare at them, it almost looks like a black layer was blended with very low opacity.
