People often say that 'beauty is in the eye of the beholder,' and I say that the most liberating thing about beauty is realizing that you are the beholder. This empowers us to find beauty in places where others have not dared to look, including inside ourselves. -Salma Hayek
Yes I agree that the composition is very good. The colors are warm and relaxing too. From the level of grain in the image I assume you either used a very high ISO rating on the shot, you exposed it for a very long time, or you pushed the exposure in your post-production software. There's a free program for download called "NeatImage" that can remove that grain and smooth out the image or so I'm told.
Silhoetted photos are fun, both to shoot and to look at. this one is no excetion, although It is rather grainy especially when viewed in the larger sizes.
