Pretty good stuff!
In general, everything looks pretty good. The animation in each is great for the most part, and the rendering is pretty okay. I want to touch briefly on each piece though:
For Sneezing: I think that everything overall happens a bit too quick, but the delivery is still present.
Elements: This one is very nicely done, seeing all these unique and cool actions going on simultaneously is impressive. My focus is drawn away though from seeing everything in the time it happens though.
Match-Cutting: This one was also done very well, and the camera transition in the action is clear and well understood. Good continuity.
Weight: Out of all of them, this was my favorite. The weight of the objects was believable and the contrast between characters helped the believability.
Lip Synch: Not bad, but I feel it could be a lot better. I don't really find it believable.
Fishing: This one is the biggest gripe I have. The proportions from start to finish are very different, as the character is significantly larger toward the end. Working with straight ahead animation, as I'm sure you know, it's easy to lose proportion, so maybe if you re-did it, try pose to pose with set key frames. But aside from that, the motions your character went through were really excellent.
Filmmaking: For what it is, its pretty well done. I'll have to watch the whole short, so I won't make any judgements.
All in all, a good year for learning I'd say, and a good demo at that.
Great work! :)
