Maurees Kramer	Nice B/W of the steel beams making the memorial to 9/11, the image is sharp the blacks and whites have great separation and contrast, the composition is very good and the buildings in the background breaks up the black back ground. It appears you may have used the lens flare filter on the buildings though you don't indicate that you did.

Eric Schweitzer	A really creative shot which I like very much. The steel beams are the dominant element and overpower the memorial walls a bit. I do not know if a greater balance could be achieved. The moon adds a nice effect and helps draw the eye to the memorial walls. I have never worked with NIK Sliver Efex Pro 2, why did you use it to convert to B&W instead of Photoshop? Well done.
Audrey Waitkus	Excellent composition, and I definitely like the choice of black and white for the presentation. I think I would like to see a slight increase in contrast and brightness (or a slightly longer exposure) to emphasize the details.
Nancy Seferian	This photo has a kind of ghostly and sad feeling for me. It seems to have a delicate lacey texture. What made it look that way? The gauzy buildings across the river, the moon and the memorial behind the steel beams add to the sadness it evokes. I guess I'm focusing on the feeling it elicits in me. As for the photo (grin), I wish I could see the end of the steel beem, but then the balance might not be as good as it is now--with the towers sliced by the beam and the moon right above of the the towers. I think this is a very special photo.
