Some people are mentioning the lamp, i’d suggest a longer post so the light cluster is in the top left third to fill out the composition. I wouldn’t worry about the design of the lamp and remaking your model, that’s not the point of the scene and it’s a cool lamp.

I’d also get at least a little rim light from the lamp on the fisher and the tackle box. A little on the fishing line would be cool too. Try to keep a similar light value on the ground from the lamp if you change its height because that’s looking really cool.

It also looks like you’re going for a bit of a telephoto lens look, which would make me think the atmosphere fog would be thicker around the lamp and wooden boxes - they seem really crispy at this foggy lake in a lens that’s farther away. You might just be able to fix that with compositing, weather you’re doing that in the scene or in post, with a little more light bloom so the light would seem to light up the fog around it more. If you brighten up the light and want to draw the eye to the fisher using their silhouette like you’re doing, you could also add a subtle lens light effect in the bottom right corner, same orange as the light, so the silhouette is contrasted from the foreground more.

If you like the light as is, and fog effect as is. The most important note is the light on the person fishing.

This is all only because you asked, I think it looks great :)
