Great picture, It has to be an amazing park, I will have to visit it some day. Henry Moore said about this work (I'm a fan of his work!):
"All art is abstract in one sense. Not to like abstract qualities or not to like reality, is to misunderstand what sculpture and art are about. Some artists are more visual, or get more excitement from nature in front of them, and then make a work of art from that. Other people do it from their insides, a more mental approach... But for me, I can’t cut my sculpture off from living, and the forms one sees in nature, in people, in trees." I like the way you have composed this image in it's setting, in nature. with tree's in th e background that compliment the subject & composition.
