the layers where then turned off and on in succession to create the separate frames in the animation. 

this method was then repeated on all frames.
i then filled in the colours using a larger brush tool on a layer in between the line art and the sketch.
i then used a black brush for the line art, and drew the outline for the image, on a separate layer above the original sketch. 
i then repeated that process on every frame, all on separate layers so the can become invisible. 
then i drew using a light coloured brush to show where the legs bend and move and used a light red to show how the clothing moves.
firstly i created a background by taking a snippet from the original.
