This is a great portrait of this crazy expression. I like the slightly grubby look of his face, and the wild hairdo, contrasted with the neat crisp lines of the cut around his ear, and the the suit jacket. It all works well together. Nice work. :)
Back to comment: What's not to love about the hair style? I find it difficult to make a connection with the subject with his eyes facing up and out of the image. It also appears as if the back (his left) eye is in better focus than the front eye. This might be an illusion related to the stronger white tone of the back eye from the side light. I bet mom still loves it.
