My oh my,the shading of this is so remarkable. It's so refined in the use of shadows, highlight, color and pencil strokes. Even the conceptual means of drawing a celebrity is clever. Also did i mention the pencil work , it clearly defines a professional artist.But of course you didn't need me to say that clearly your already aware of your talent. The mixing of the colors seems so delicate. How were able to layer on the colors so delicately.The way you executed this so elegant and full of taste.
