Rename the shot, it should be called horse and girl
The horse is main subject to me, it looks sooo satisfied with life. The girl is a suppoting subject. The story may be a bit carelessly told since the horse is darker than the girl and also not in focus, but in terms of expression the horse is telling a great story. As for the examplephotos from harv, They do not work for me. The horse is not connecting. The girl is ok in the first shot but is facing the harsh light in the secind so she has to close her eyes.
My advice to Hammar, use a larget dof . Its a two subject portrait and both should be sharp in this case. Advice to harv, start with finding good light and then try to get expressions from your subjects. And if I stepped on toes now, I did not mean to insult anyone. Keep on shooting horse-hunan portraits. And merry christmas
