Kitten's Playroom

This Illustration called "Kitten's Playroom".I made this with oil pastels(crayon).

at first I choose a medium paper board which doesn't have any texture and it's completely smooth.then I started to color different part of the paper with different colors till all the paper was colorfull. then I filled the paper board with black oil pastel and put the design on it,I started to line on the main design which is on the colored paper board now.for the last step,I scratched all of the lines from the main design to made the colors appear.
