Subway Line Animation

LOOKS GOOD. Other than the flickering, which looks to be localized to certain materials, I would get rid of the vignetting on the camera & add it in post and feather it in better/smoother. use a longer gradiant path. If you did it in post then just do the last part I suggested. I also saw some frozen people in a walk movment. If you have moving models in a scene then anyone stationary should look to be just standing still.

nice job, just one comment tho. You should fix the flickering images by calculating the illumination pass first and then making the final render pass. Not calculating each frame individually. other than that,... great :)
