This image is, by far, one of the most impactful pieces of art I've seen to date.
There's something about images with big walls and little people that's very striking to its audience, and The Black Wall draws out the essence of this fascination.
The feature that stands out the most is the lack of a landscape - shifting the focus directly to the wall and the model, and not allowing the imagination to stray too far into what lies on either side. Yet, the lack of this feature performs a sort of reverse psychology on the viewer, enticing the imagination.
From a technical aspect, everything is squared away very neatly and realistically. The shadows are perfect, both for the wall and the model, and the shape of the wall brings out the feeling of distance -- a necessary component to the image. Additionally, the color compliments the textures and composure perfectly.
Overall, everything is rounded up with the description. With Gaza as an intent, the image becomes VERY realistic. The surreal becomes real. Wonderful work!
