We like these designs because they convey luxury and high quality. They are also elegant, and easy to read and comprehend. We also like the pictorial mark.
Our favorite is Entry #58. We'd like to see this as a linear mark, similar to Entry #59 and please include the Registered Trademark symbol. We can definitely see using a combination of Entry #58 and #59 or in some other color combination.
Of all your logos, the one we like least is Entry #68. It seems a bit harder to see the horse in the pictorial.
