The B&W just accentuates the few things I felt were weaknesses in the image, the merging of the top of the Rhino and the grass/mountain line and that dark bush which is too close to him and unbalances the image.
My vote also goes for the colored version. I have to say I agree with Robert and I think it could work better if the rhino was a bit lower in the grass. Nice to see these guys out there. TFS.
