Hello Vianna:
Very nice work, I particularly enjoy the lighting. You did a nice job modeling the forms on the shadow side of the face.
How long did this take you?
It may interest you to know that a lot of studios are painted a mid to dark green also. My studio is. The color came from Bill Whitaker who got it from David Leffel - it is the color he used in his studio and at ASL in New York. It looks wonderful against flesh.
