It's nice to see some nice traditional frame-by-frame animation here on Newgrounds. My only suggestion for this would be to add more inbetweening, as the end result is much smoother.
Though there seems to be a decline in the way you chose to present these randomly placed sequences. Particularly, I'm talking about Pacman, the sun and the clouds and how you repeated them as frames.
I understand the feel you were aiming for with this, because I too tried to make a flash like this called "-Abraham-." It received bad reception for being too randomly placed. As with this - it didn't maintain its consistency as other fbf animations do and after the color feels out of place.
Though if this was a showcase for your animation skills or the song, then it fit its purpose and perhaps I'm being a bit too critical of it. Good luck on your future endeavors.
