A Brilliant Visual Joke!
I really like how it was animated - not too sketchy (but not entirely the best, either). I also loved the visual joke of having the R + R sign, how Angry Face falls in love with it, and then, at the perfect moment, BOOM! Angry Face gets hit by the train. The music was brilliantly used, as well. I just had a few problems with it: 1) The jokes were obvious and you could see them coming. and 2) It was a bit short (but with this kind of plot, it's fine).
In all, good humor (although it was a tad obvious), good music, and, overall, a good Valentine's Day flash
Nice Work!
