I agree with jeff here, but I think if the guy was to just stand there, no jumping, and standing upright, but facing away from the camera, have him just looking out into the distance. I also think the wagon, or trailer, whichever one it is, takes away from the picture, it draws your attention to it, when IMO the attention should be primarily on the person. I don't know what is to the right, but if you could I would try to make it so the trailer isn't in the frame next time. And yah, I think they would look really good in b.w
Good work
