Here used shading to block in silhouettes, ears, feet, leg positions
Here blocked in a foreground and background doodle, little perspective, used shapes to fill in areas
used a photoshop brush to block in rough features, characters and bg
darken some areas
add doodles for some dark areas and eye white
tried framing a little by making a black layer on top everything, selecting center area with marquee tool then deleting. Then by moving this layer its like framing the shot. (the missing black areas were filled in with magic wand)
