My first shot at a realistic person; Walter White (a.k.a Heisenberg) from Breaking Bad (played by Bryan Cranston). I wanted to try something new, because I was at a mental block for a while. I didn't pick up a pencil for three weeks. I guess I worn out the "video game fanart" for a while and expanded my interests. If you don't watch Breaking Bad, do it now. Like seriously, I'll wait. Go get Netflix and watch it right this second. Highly recommended.
