The animal's head's getting lost in its torso. I love the detail in the barn. I feel like a little bit more contrast (and some selective dodging... which sucks we couldn't do) would have done this photo well. 6
I have only one problem with this; I think you should have waited thill the cow had it's head facing the barn then it would have been EXCELLENT! (Imho) Otherwise lovely barn and scenery. I'd love to photograph it myself.
