Thankyou for your entries. I like entry 5 but I would suggest the following.
1) can you not fill in the horses head. Just make it an outline that is the same line width as the circle 2) I would like the horse head to look more like the head of the horse in the link below 3) make the word Eykamp and the logo a baby blue 4) make the word Kadi a navy blue 5) drop the word Eventing a little lower so it is not so close to the letters above
