Photo Analysis: A London Night

What works well:

Compositionally, the lamp is a bit of a double-edged sword (more on that down below), but on the positive side it absolutely works as a spotlight device. Your eye goes straight to the lamp first, and from there naturally down to the man underneath it.
Framing is solid overall. Our subject sits nicely between two posts, which subtly box him in without it feeling forced.
The man and the lamp are both off-centre, which keeps the composition from feeling static or overly symmetrical.
There is also a subtle line in the street pointing directly toward our subject, acting as a very quiet/subtle leading line that supports the composition.
The layering works really well too → street in the foreground, posts, then the man + lamp, followed by the river, and finally the skyline. This gives the photo strong depth and a nice 3D effect.

What could be better:

Because the lamp isn’t a strictly overhead light, the pole of it sits directly behind the man. This hurts subject separation quite a bit and makes him blend into the background more than ideal.
Background separation on the subject in general is the weakest part compositionally. Not only the thing mentioned above, but also the dark jacket and trousers of the man don’t help. But of course that aspect is obviously not something the photographer can control.
The lower foreground might feel a bit visually empty to some people compared to how much is happening higher up.

What works well:

The warm light against the cold blue sky and snowy environment works beautifully and reinforces the classic winter-(early)evening atmosphere.
The overall mood/atmosphere feels calm, quiet, and slightly melancholic, very much a ‘long day is over’ kind of feeling.

What could be better:

The shadows are a bit heavy in places, especially around the lower half of the frame, which eats into detail.
The brightness of the lamp slightly overpowers the rest of the scene, making the balance between subject and light a bit uneven.

What works well:

We do get some nice storytelling clues here. It clearly feels cold and late —> the snow, the blue hour light, and the overall quiet street all sell that instantly.
The man also carrying a work bag strongly suggests he is heading home after a long day.
His posture and the turned-up collar support the idea of cold weather as well.
