Great use of lines and UWA POV to draw the viewer in. Good light and low POV. A slight sharpening or JPG reduction artefact on the right of dark trousers.
Interesting viewpoint you have chose to capture a very artsy scene - looks like a photography exhibition. Did you find any inspiration, or did you perhaps have work on display? TheWB is a little warm, but you may have done thtis on purpose, since it does fit the image nicely.
It always is very interesting to see how lenses "distort" reality, or, to realize how our minds adapt to what our eyes see (closer things bigger, same size things further away much smaller, perspective that is) and tell us they are the same size even though they look so different.
Love the overall color/feel of this photo - the man is interesting looking with his greying hair hanging down but still not taking away from his look of being a scholar. It looks like he is reading something rather than looking at the art - a sparse gallery which adds to the appeal - as if it must be a juried gallery and only works that pass muster are allowed to hang in it. Quite the story you have started in my head.
