Baifern Pimchanok

I just finished this portrait last July 9, 2011, took me almost a week to finish it, 2-3 hours each day This is not my first portrait, but i think this is the best portrait drawing i made so far. I'm just a beginner, i still need to practice but hope you guys like it
Drawn on a 8.5"x11" bond paper. I used regular HB pencil, and some kind of eraser i found in my pencil case
