Analytic Drawings - Sketchbook

I love to use pens to record analytic drawings when in the observation process during project. When applying this material I initially start off by sketching the image out by using pencil this allows me to understand the proportion. Then when correct, I will apply the pen this allows me to push the tone and depth. While doing this I work with 3 tones, the pen being the dark tone, the pencil being the mid tone and the clear white sketchbook paper playing as the light tone
