I think it looks great!!!! Love the opening shot of the desert.
Here are two things that I noticed:
I clicked on your stallions link and was like okay, what the heck its not loading, is something wrong with my connect? Then I clicked again and again and again until I realized that it was loaded onto the page and had to scroll down...LOL That maybe something to think about.
Then the quality of some of your photos, not the animals in them, but that actual photos. Could you have them restored?? I think that it will make a hell of a difference!!
Otherwise your site is great! Great visually, no crazy colors, etc. I also think blue is a color that is most easily read by eyes.
AWESOME JOB!!
