Very Well Done
I enjoyed the detail of the art (I belive it's pencil?) and the great use of the Ken Burns effect. It gives a great feeling of sympathy for the poor mother as she loses her newborn.I did notice that in a couple of scenes you decided to reuse certain drawings to complete the plot. I also noticed that the first drawing of the reaper differed from the rest of your drawings mainly in the face/hood.
Overall, I enjoyed this. It brought me back to High School Television Productions Class. I would enjoy seeing more films like this, it seems to suit your skills well. Some advice is that you could use a little less detail for less important aspects. Might help with that file size. I might also suggest that you create a character on a seperate sheet of paper, giving you a chance to iron out the details.
