A very strong portrait of this American Bison. I like the intimate crop and pose as well good eye contact but I find a couple of the tall grasses on the left and one on the right a little distracting. The shorter grasses are lovely as a touch of the environment many times adds to the image. The last thing I noticed is it looks slightly over sharpened. Thanks for sharing this with us.
I like the way the bison looks into the frame and you left some room on the right side of the frame. The FG grasses are a problem. Overall I think the framing is to tight. I think I would have liked a lot more room on the bottom of the frame to include more of the bison..
