Honestly, just a portrait of her, minus the beware of dog part, would be way more interesting to me. Have the focus of a shot be completely on her and you have something to work with versus her sharing viewer attention with a door? Nah. Stick to just her.
now if this shot had been done with her holding back a dog like a pipbul who looked well p*ssed the shot would have worked a lot better. i agree though a portrait of this model would have looked better, shes good looking but the door kind of steals attention.
