This image is too small to see the details which I'm sure are quite interesting. Check out this tutorial for resizing for DPC. //www.dpchallenge.com/tutorial.php?TUTORIAL_ID=26
I am sorry this is so small. I believe there is a great image here dying to get out. Next time, if you can, try to use all the pixels available to you.
Cool idea. Could be larger, though. There are lots of fun angles to use on lighthouse lenses. Also, the light from the window is so white it distracts.
This image feels rather tightly cropped, more space around the lens would make a more interesting image. Also the posting size is so small, its very hard to see the details. (you can post as large as 640pix on longest side)
