I thoroughly enjoyed this short animation. I thought the transitions were very fluid and the colours were everything but lugubrious ;) The animation really warmed my heart, alas, there were some elements which prevent me from giving it a 5 stars. For one thing, there is too much repetiveness towards the end, which then stagnates the flow of the film. Anyways, I don't want to critique the animation too much as it is evident that you spent a long time on it.
My rating: 4/5
