I know this is moving kind of slow but I decided to take my time with this one. What I'm drawing means a lot to me so I want to get it right!
By the way-when you only have balck and white-it is extremely difficult to draw open mouths...You have the outher lip which is dark, the teeth which are light and then the tongue which is dark...but everytime you draw the tongue and leave white for the teeth, it looks like a duckface because you cannot recogize the teeth...
No I'm SERIOus! it's a problem!!
