It was pretty good.
It was a pretty good cartoon as far as serious animations go. The rain was extremely well-made, and so were a good handful of your character shots. My only peeve with it, and this is only my opinion, is that it's slightly cliched.
Also, in my opinion, you'd get a lot bette scores if you hadn't ended it so soon. By ending it only where the action starts and not giving the watcher more of a taste first, they don't look forward to the next one as much as they could, or should.
This cartoon was pretty nice, and I like your drawing style. Can't wait for more.
