Preston Blair Top hat gentleman practice

Next construction of head practice.
My image at left and Preston's at right.

Below image is Preston's in orange and my attempt in blue. Sorry that it's a bit hard to see.
What errors that strike me most in my attempt are the face is longer than Prestons and the negative spaces between forms are to wide. Not in all cases, but more than enough.

For Preston's image I have put in red lines which denote (guide lines) and the blue lines are for the negative spaces (or gaps between forms). By doing these two measurements I could more closely see where I had gone wrong in copying Preston's work.

For now I can see that my negative spaces are out. And I think this is related to the fact that my face shape is vertically to long - which then pushes all the other elements out.

**Noticeable areas of error - my ears are too small which then makes the hair too long. Also the negative space between my eyes are too far apart - even though the placement of the eyes are fairly close.
Well - that's that for now. More to come soon.
