anamorphosis drawing

First i found an image of what i wanted to do for my anamorphosis and then transformed the scale of the image in  photoshop to where my picture was elongated.  Then i drew a grid on the picture and in my sketchbook so i could sketch the image in the appropriate spot.  I colored it in with colored pencils and added different values to my sketch.  I added a shadow in the back to show the picture was standing up and took a picture of it in a place where it looked like the sketch was 3D.
