Oh... I like the angle you've taken the photo from but to me, I felt that you tilted the camera a bit too much. Also, some parts of this photograph are fairly dark, especially around the corners. Did you use flash for this?
Not bad composition But I think you didn't need to make so much vignetting effect. And also your photo is too dark. I think so because when I first seen this pic I noted only clear wall of this building and other things that could make your photo looking better are hide by vignetting and darkness.
I am supposed to comment on this one cause I like it a lot but the problem is that I am speechless! It is simply stunning! The angle of the shot, the lighting, smoothness in the colors, everything is just perfect. No wonder it has 80+ favs
