Face or a Tree illusion

Is it a Tree or a face of a person? It is Definitely a Tree. what do you thinks it is man made or Nature made? The tree has had its branches shaped so that it resembles a face. It makes an interesting picture and makes you wonder what this tree would look like with leaves on it. and i m confused about the face i probably think it is a face of David Duchovny but i m not sure, if any body know then let me know
