This is a very interesting view point of the person standing in front of the white horse. There are a few composition thoughts you need to keep in mind. Every picture should only have one focus. This picture seems to have two focuses; the person and the horse. Is the horse the focus? If it is then the person should be in a different place. This picture has some mystery surrounding it which makes it very intriguing and interesting. Also, you need to work more on the changing values to give the animal a more dimensional or realistic look. It is an excellent beginners picture. Thanks for sharing it.
