Great shots - both. I have a preference for the first, partly because of the pose struck by the bull (nice posing!) and also because of the presentation. If there is one niggly... after having a good look at the bull, I find my eye looking to the horizon and being distracted by the faintly visible poles and lines. To some, the tree may provide a counterpoint, but to me, it is also pulling my eye away from the details I should be looking at (and I don't mean the jewel sack!).
