Well- only the fog was already one hour tweaking-
We know it is hard to do.
The street light are to white for me personally (but nowadays we have led lights, so maybe it is correct).
Yes great fog there! Seems just right.
Those are great renders! The last one looks almost like some grayscale photo of a bridge! Good job!
I’m really liking the first render. The bridge, lights, and the water all look so natural. Well done in my opinion.
