Absolutely Masterful
I haven't written a review in a long time, but this was so wonderfully conceived, created, and executed that I couldn't contain my enthusiasm. I don't really know what to say: the animation was smooth, nearly flawless; the music was excellent (particularly how you matched it with the animation); the plot, while simplistic, was nonetheless nicely done for a few-minute cartoon. Really, I don't think I could give enough praise to do this justice. Rest assured, it is now at the top of my favorite's list (a very exclusive list).
I see you as having a promising career in animation, my friend. Let's just hope that some jerk on YouTube doesn't post your creation as his own.
