You did a really nice job with this frame by frame
Very very original idea, and I liked how the overall mood of the piece blended in with the music. The frame by frame was very good, and your stick figure had alot of character despite of... Well, being a stick figure. You did a nice job with the theme of the animation, and the frame by frame was good. I could see that you spent some time on it, and I hope that you get to do alot more, especially if your quality improves. Who knows, you might hit Daily Feature or Weekly some day if you get better!
My only critiques is... Just color it, or make a little bit more detailed backrounds, or make the story a bit longer with a bit more depth of the character really attempting to fly. Also if you would have made the wings a bit better drawn when he flew away he was standing, usually you just float. So try to bring more life into the stick figure by giving it human characteristics. Otherwise I like the fact that everything else is muted but the music. Great job!
