This composition has several key elements that influence the creation of the atmosphere. I think that the line is the main component. Their abundance together with the main lines (which form A) make the image non-standard, exclusive. The second in importance I consider light. Light emphasizes some lines and hides other lines. It makes the atmosphere more mysterious.

And of course the third main component of the image is the pigeon. The dove is in the shadows creating a feeling of its own independence from the surrounding situation. It is lonely and has a white spot that makes it unlike, unique. At any moment he can spread his wings and fly away. Therefore, in the context of this image, I see it as a symbol of freedom.
Pigeons are good birds which are called the birds of the world. Good job! I liked it, thank you!
