This is a good example of a classic perched bird shot, demonstrating a skilled hand. The light is coming slightly from the left of the frame, and the photographer has wisely waited until the bird turned its head into the light, avoiding unwanted shadowing in that crucial area. The overall exposure is well balanced, and I like the inclusion of the reed stems as they hint at the bird’s natural environment without becoming distracting. I’m not entirely sold on the square crop, however — a standard vertical or horizontal ratio would have been a more natural fit for this type of composition.
