Since you asked for some Constructive Crit, I shall offer
1: I really like this one for it has a dynamic feel due to the playing of perspectives with the lights, tunnel, etc. It gives a sense of being busy, while also being calm, waiting for the trains. I think it is kind of refreshing to see a subway "view" shot like this, that isn't a long-exposure with the people's motion blur.
2: The exposure of this one is perfect, but the composition is, to me, confused. I'm not sure of what to look at because there is so
much to look at, but nothing is exactly eye catching except for the poster...In short: I don't know what you were trying to convey with this picture.
3: Again, as I see it, I don't understand the interest of this picture. Nothing really pops out at me as being of great interest. If you wanted to show the sign, I think it would have been better centered, as opposed to being offset as it is.
But, this is a suggestion for you, because there a
VERY interesting element in this picture, and that's the middle window at the top of the picture. The reflection of the dead tree branch over the white flowers. This I feel, would have made for possibly, an amazing photo. IE: GO BACK THERE! TAKE THAT PICTURE!
Always keep your eyes open. I know you probably didn't even notice that while you were out there, taking that picture. I know I would have missed it myself. I know that I need to slow myself down and analyze what I am seeing for what would mak a great photograph.
4: I like it. It's hard to describe why, because I also feel that it is missing something. Sorry I can't be more help on this one.
5: I love this one! I am a nut who loves urban decay, and contrasts of new and old. So I guess that's where my love of it comes from.
Anyways, rusty fence is, perhaps slightly under exposed, but I feel; that is what makes this shot. It adds a slight darkness to the mood of the picture, in contrast to the bright new chain and lock. There is only one thing I would do with this, and that is crop off the top of the image, from just under the bracket on the drain spout on the building. The fence is the dominating factor of this shot, and I think it needs that extra focus. Leaving a bit of the building above it to give it a height boarder. I'd definitely hang that on my wall
6: 1 thing only that I don't like, is that light beam on that bird's eye. Unfortunately thats out of your control, but all else about this shot I love
The only thing I think that might have made this shot better, is if the background was a bit more out of focus, more "bokeh" as it called sometimes. I think that would help the birds to "pop" a bit more. Just something to try next time you have a situation like this.
