Speechless is a perfect title for this entry. I am surprised to see so many of this type of picture in the challenge, but this is one of my top 3 over-all. I love the dirty grease look of it and the position is good. I don't know if the red panel on the left side is adding much to the over-all shot for me. I might have cropped it out and presented a vertical composition without the tilted line. It might help simplify the shot and keep all the attention on the subject. I don't think one can truely appreciate a "faces shot" until they actually take the time to hunt for one. It's not at all as easy as it sounds, is it. Over-all a great shot for this challenge.
what if you crop the whole lef side of the image to eliminate the curved line of the window? even though it centers the face, I think it would make to composition more interesting. wonderful face, too.
