Roto Brush example tutorial from After Effects

Here is the Roto Brush example tutorial all complete. I also changed the colour of a flower in the background. :) This is an exported version from Quicktime Pro as a Mpeg4 with the H264 codec. It's image size was originally 1920 x 1080, but I decreased it to1280 x 720 for easier viewing on here.
