When I look at your photograph, I see something that might have a use in a business card. Considering the prominence of your logo, it seems ready-made for that.
However, looking at the remainder of the photograph, I would say there is not a "subject". A herd can sometimes be called A subject, but then you probably wouldn't want the water tank in there.
In addition to better light, try to isolate a subject, whether is is one, two, three, or more animals; the natural grouping of a subject should be more clearly defined.
Then, crop to emphasize the subject rather than sky and grass.
I don't know why you want such a large intrusive logo (or even a logo at all, for that matter) but perhaps smaller or positioned in a different part of the photograph.
To summarize:
1. better light
2. better composition
3. less logo
