#2 - love you melding of the horse and horizon aspect of the businesses' name. Can you try a solid blue horse (silhouette - with white lines for some aspects of the mane, etc) and then a warm yellow sunburst behind? Not sure about the font, but don't have any concrete requests for what to change it to.
#6 - really like the blue horse and brown sunburst (favorite of all your versions) - but nix previous font comment and let's see #2 font back with it. thanks!
#12 and #13 - like it, but can't decide about the underline bit or not. Now - the horsehead - can we see a version where it's more of a silhouette form without the flowing mane aspect?
Sorry. Something like #15 as far as a horsehead. It's hard to explain, but the beautiful head you are using looks like a breed of horse that is not really the type that we have in our program. The one you are using is a beautiful horsehead, but not quite the right horsehead. Go back to your #12 version, but see if you can give us that horse without the mane (hair). Does that help?
