To do this I used muddbox and maya to shape and mold a base head model into more of the look of my face. I mostly use the sculpt tool to sculpt out the face or invert the tool to sculpt in the face. I used the grab tool to pull out edges, and I also used the smooth tool to get rid of any rough edges that appeared as I was sculpting. For more help in making the model I used a stencil of my face as a basic outline.
To me this still needs a lot of work, and various things need to be added, like hair and the textures.
