The scenes started to get monotonous after a while, as they all revolved around Andy expressing guilt about Warren, or being tormented by Warren. Every scene had exactly the same mood, to the effect that it was akin to painting a picture with only one color of paint. It would be better if you had added some variety of scenes with different moods in there, not necessarily positive moods, but just other moods to contrast with the constant guilt that Andy feels over Warren.
