Drawing Progression

I like those videos where you see a time lapse of a work so I decided to make one. This is a simple two-point perspective with a figure sitting on it. It's starts as a light pencil sketch and I begin adding more and more ink. It's just mechanical pencil and Sharpie on 8.5 x 11 printer paper. I took the pictures with a cheap digital camera and compiled them on a windows movie making program that came with my laptop.
