Wow....
That was amazingly well done. The whole feel of the animation was very powerful, and conveyed the moods perfectly as needed. It's evident that you put a lot of time and effort into the graphics, as they're well-drawn, flow well with the music, and the colours show a vivid contrast between the two main characters, adding emphasis where necessary.
I'd like to say more, but I can't really express how much I like this piece in words. I knew you were a quality artist from your recent works, but I didn't realise that you were capable of something this well crafted... you're going on my favourite author list, good sir. =)
By the way, I can't help but ask, would the 'successful' character's works be a reference to a certain overly popular and angry squirrel, perchance? ;)
