Truly good conversions to black and white are difficult and this is a good exmaple of the zone system and how it impacts an image. In this instance a technical success isn't quite the artistic success it should be. While a good candid look at an introspective moment, the subject is short of having some sort of pop or wow factor that provides the image with some impact - it's just a candid moment. While photographers can't always be in the right place at the right time with the right camera and the right lens, this might have been improved by a crop of the top to make the image longer and giving the image a sense of dimension - while detailed the background is overly detailed and detracts from the image's impact. The author should experiment wtih varying top crops to get the best effect. A good solid entry into the challenge.
