|Greetings from the Critique Club!
This is a very striking image. Let's dig a little deeper, shall we?
Focus: The focus on the first face is excellent, very nice textures and detailing shown. The ability to see the pitting really gives an added point of interest. That said, I find the limited focal range - specific only to the first figure - to draw away from the essence of three. The image of course does have three obvious subjects, but I think a deeper focus would pull the other two figures in more and highlight the three aspect to a greater degree.
Color: The color is wonderful. I love the cool, dark feeling of it. Gives a nice stone atmosphere, and the color reflected in the background adds a nice touch of melancholy to the picture. The darker tone really plays up the melodrama.
Composition: I like the composition, however I do agree with the previous commenter that it would be nice to see the third figure just a bit more. This also falls in line with my mention about spreading the focus out more. Other than that, the composition is excellent. Its uncluttered and free, really helps play up the color/tone usage and allows the eye to focus on the great detail you've put on display.
All in all this is a very solid entry and I'm surprised it didn't do higher than 5.3. I find it humorous and dramatic, it really caught my eye. Your work on the background is very nice and enhances the image rather than overshadowing or overpowering it.
Very well done. Thank you for such a pleasant image to critique!
