This photo is good. It gives the appearence of abandonment. My eyes travel from the fountain to the bars then cut across the image. Also the contrast of the dark trees and the white sky helps out as well.
Beautiful picture, not a bit of blurriness all the shapes create a circle that my eye keeps following. I also think the lack of color works in this instance.
Why sadness? Looks like a nice park to me. I like the black and white. There are few too many things in the frame for me to look at... not sure where to focus. The main subject seems to be the slide which is smack in the center of the image... nice if it was off center.
Well photographed, but it just doesn't have the 'punch' to excite me about the scene... not a clear subject. Perhaps an adult or dog in the scene to draw the viewer in?
