Minor - Character Head Modelling Progress (Scientist)

I have been modelling the head shape for the scientist characters. Since their faces are covered from the suit, I have had to take a different approach to modelling the head shape. Despite the simplicity of the shape, I have had to spend a lot of time sculpting this to create the shape that I will like. There is still much to be done for the head, including building the visor, reshaping the head and smoothing the lumps and bumps that still appear on my model.
