My Subtractive and Additive Drawings!!

Here is my subtractive drawing:

file:///Users/student/Desktop/Photo%20on%2010-29-13%20at%208.49%20AM%20%233.jpg



This drawing was very difficult because I had to erase the parts of the drawing that had the least amount of light.


Here is my additive drawing:

This drawing was easier, but I am naturally a terrible drawer, so that didn't help!!

If I had to choose one or the other, I would probably choose the additive drawing because it gives you a better command of the image.
Subtractive is a very different way of drawing and it tends to do better with shading. Both ways are good, and both ways offer pros and cons.
