Tiny image, but looks well composed. If you use Photoshop, try the "Save for Web" feature and save it as a jpg. Adjust the quality level to as high as you can to come as close to the 150 kb max allowed for the challenge. You can also adjust the image size and dpi.
This photograph is just too small - DPC allows a photograph to be up to 640pix in either or both directions, and a photograph this small is very difficult to see. I do like the content - composition looks ok, but again, it's hard to see.
This looks like a beautiful landscape shot... i really like train bridges :) I think the image would have more impact if it was a bit larger... nice work :) - setzler
very natural setting and nice perspective. its too bad you caught the edge of the path on the bottom left corner. also, i think you're hurting youself by not submitting the photo at the max allowable size. did you consider increasing the saturation levels in the post processing to try to bring out more the green in the trees?
why so small a picture here? You're allowed 150K. This seems dishonorable to your photograph, it's so small to look at, you can't really see it to make any good comments.
Nice shot but why so small? I'm sure this is a much stronger composition when viewed larger. I can't see much detail due to the size of the submission. When possible try to submit your photos at the maximum 640 on the long side of the photo. Good luck with the challenge!
