Something is off about the hind end to me (weak coupling?), her neck is under muscled, her shoulder seems steep to me and her chest seems rather pointy (Pigeon breasted?). The whole image is of a horse that is under condition. She seems over at the knee which would make me question how she would hold up to the challenge of eventing. Color is as color does, for eventing I would look at the task at hand over color. I have color lust for a palomino, so I understand the appeal. That said if you are serious about eventing and serious about a cremello I would keep looking. I don't know that I would waste the gas looking at this one. I don't know much about conformation I just don't like much about this mare.
