Concentration Piece No.1 Update

I have started to review my current and master artists to see what influences can help me in the finalization of the style that I want this piece to have. Leonardo Da Vinci's, "La Bella Principessa", serves as a great study for getting a proper head shape from the profile viewpoint. The current artist, MO Knows Art and Design, has a piece titled, "Credence Clearwater Revival", which is a style that I have always wanted to try and so I think that will be my main influence for this piece.
