Scratchboard Project Einstein

A recently submited project for a presentation and design class. This was a scratchboard/clayboard project. The reference photo used is of Einstein by the famous Yousuf Karsh. Metal tools and iron-like wool was used to scratch the ink off the clayboard, and I used inda ink to touch up my work, as well is watered down india ink for that ink-wash feel to the shadows later smothened out with the tools.
