Tedd Vallance is my step Dad, you may have see his work at United Coffee in Sacramento, Ca. I was finally able to get him to start a blog in which he explains his process and motivation. He spends 40 hours or more on one 8x10 drawing. As a child he made sure I always had plenty of art supplies, everything I could possibly need. I was always in awe of his talent, skill, and patience, and so I am excited that he is finally putting his beautiful trees out there for all to see! Follow him!
