When i was doing the Anamorphosis drawing i had to use Photoshop to make the top larger so when you looked at it at the right angle you could see it is in perspective. I had to make a grid so i could take the transformed picture and put it to scale on the paper. 

The colored pencils anamorphosis had to be a grid in both the actual picture and the drawing. I added shadows and value to make it look like it is coming off of the page. Mine was hard to draw all transformed and stretched but in the end at least you could tell what it is.

The most important part of my drawing is the color I think. It is important because if i didn't have color then you couldn't tell what it was.
