Don't take this the wrong way but as I see DPC as a learning experience here is my frank critique:
This comes across as a snapshot. By that I mean that I feel that anybody standing where you were with a camera could have gone click and got this result. I think a photographer should aim to do more than that. I may be wrong and perhaps you do have more of a story to your shot but the fact is that it doesn't come across to the viewer.
As an example, if you were in Paris and saw the Eiffel Tower you could hold the camera and go click. You'd have a shot that millions of other tourists have and would be good as a record of your holiday. I think at DPC you need more than that. You need to consider the POV - make it something that enhances the tower (include a flowerbed or kissing couple in the foreground), make use of lighting (dusk for shadows), composition (maybe include the buildings beside it to get a sense of scale).
I hope this helps and please don't be offended, I'm only offering an opinion.
A bewitching photograph. Laden with metaphor and irresistibly inviting for the viewer as well as for the boys. It's the thing I love the most about photographs; a brilliant image that doesn't look it, doesn't look like a conventional photograph at all. An anti-photography photograph. I think that every adult can look at this and remember the same enchanted moments from their own childhood. The forest may have instead been an alley, or a big park, or some other forbidding place, but the moment was the same as this. From light into darkness, from certainty into doubt, from the familiar world into the unknown; each standing on the courage of his friend. Neither could do it without the other. We still do this, no matter how old we get; it's who we are. And thank Goodness for that. 10. And also the ultimate mark of DPC obscurity, the Order of the Thumb:
The angle you are shooting from, the size of the trees, and the distance shown on the trail makes these guys looks so little and vulnerable, yet they are "marching" on despite it. That's how we have to approach life somedays.
I'm not sure about the B&W on this shot, because the path is really dark at some parts, so as some trees. I like the idea, light and composition. Good luck.
