I like the concept, but it seems too busy to me. Why the puma and the snake piled on top of the "main characters?" The castle doesn't fit at all with the Western look of the rest of the image. The name is tiny. On a small logo (bottle label) it will be lost. The outlines on the lighter horse are too faint in the first image.
I say drop the non-equestrian animals, scrap the castle, enlarge and stylize the font across the top of the image (centered) and make the outline colors of the figures/horses consistent/darker.
How's that for directions?
