Definitely alone and fits the theme. However, there isn't much of an impact. Even the b&w tones are a bit washed out. You may want a little more contrast to really bring out the subject of the photo.

The juxtaposition of the urban and the rural is interesting. You may have been able to focus more on the sheep with a shallower depth of field. Placing the centre of interest some place other than the middle of the frame would have improved it for me.

The sheep is standing by itself, but so what? This picture just doesn't draw me in and the roofs in the background are distracting. If there were some other sheep jumping over those roofs, that would be darn funny though.

A humorous scene, though it doesn't say much else to me. Just one person's opinion :-)
