I really like the flyers, but very much like the 2nd one best. I am very much a picture person, and can be critical. I just wanted to point out a couple of things if you were thinking of using it for advertising your stallion. First of all, I really like the overall balance of the 2nd flyer better. Also (here is where I get picky) on the first one, I can tell one of the pictures was flipped. Because if you look close the facial markings are not the same and I believe he has one blue eye and one regular? Between the 2 pictures they do not match. I would be carefull "flipping" photos of a horse that is not solid or has different colored eyes. Especially if you were going to use them for advertisements for breeding or for sale. People will get a sense that the horses are not being represented honestly. I know this is not the case, just wanted to point that out. On a solid horse it is much easier to do so.
Your friend does nice work, and your arab is awesome.
