Absolutely super composition....the color in the sky even makes a nice arrow saying to the viewer, "Look Here". I also like the light parts of the sky once this pic is inlarged...reduces the "dark" feel that one gets from the thumbnail. The pennant at the right contributes interest and is well placed. If it were my photo, I'd clone out the smaller pennants at the lower right because, although one can figure out that they are slack pennants (no wind), they do distract the viewer from a full first impression of the sunset (sunrise?) until they are understood.
The lighting is very good, the placement is good, and the composition is great. It is a little dark, but that kind of adds to the dusky, twighlight feel of the shot. I can almost imagine that I am in the place of a knight looking up past the pennants the night before a battle or something. I like it! Good Job.

P.S. If you get a chance, take a look at my gallery, and let me know what you think of a couple pics. Any comments, criticisms, or advice would be welcome. Have a great day!
