Ranka Lee Drawing

As promised here is my drawing of Ranka Lee. Sorry I posted it kind of late but it is in. It is not yet finished, especially since I am experimenting a bit on this drawing. For a change I decided to actually use some color. So since I think I have a hang of drawing with out many mistakes now, I am just drawing it from scratch using color pencils. Making mistakes now could pretty well cost me the drawing so I have to be extremely careful. What do you guys think of it so far?
