I think the window glow looks pretty good.
My suggestion is on the compositional side: The lighting on the humanoid lacks a physical source, so the highlight looks out of place as if the figure was composited into the scene separately. If you can think of an object that is casting light onto the humanoid and place it into the scene (a neon sign, light spilling from a rooftop access door, etc) everything would fit together just a bit better.
Another thing you could try is looking into 3-point lighting used in photography and film. Different 3-point configurations on the humanoid could help make them stand out from the background while keeping the highlights more subtle.
