I was assigned to develop some concept art for a web show. They are currently going for a late night talk show style set, this is what I came up with. They wanted 3 samples of each set. Please let me know what you think. Thanks.
Your first picture it does not look natural because the skyscrapers leaning the wrong way. Causes people to become dizzy.
They should be lined up with the window frame, I think.
In the second picture, it seems that the brick wall is a little thin, and the skyskrapers seems leaning backwards.
On the third picture, I wonder why there is glitches in the window frames and glass surfaces seems a little grainy
Otherwise, it seems that the rendering is good.
I like the first scene and its lighting the most. Scenes 2 and 3 are good too but in scene 3 the lighting is bit darker then others and the grey window decor you putted behind look bit not suitable to overall look of your render.
