The green scene; I think the lighting is too monochrome, maybe try adding some lanterns with another color or another green, play around with it.
The second scene: make the lamps flicker A LOT slower, they feel epileptic, but else I like that scene.
Fourth scene: I think there is some flickering meshes on the left side of the street when the camera pans upwards - fix it!
And lastly I want to add a personal preferance about the camera flights; I think that you should try to avoid to quick movement as well as having the camera completly still, keep it moving very slowly instead.
