Someone who will remain nameless  gave me a challenge to make Scream.
Here are a few variations and changing him slightly as we went.

The eyes/nose section were not to great in first picture.
Second picture eyes/nose section a little better.
Added extra white to forehead and around mouth in picture three but then
not enough black showing at top of head on picture three.

Picture two was my favourite at the moment.

So we took away the white around the mouth and made the 260 at top of head narrower and added a 160 right at the top as well.

Still has work to do and my next idea is to use a White round for the top section of the head.

I got side tracked with using a round for the top of the head and tried a Geo blossom instead.
On the first picture the Black around the outside was a 260 and to bold so went for a 160
on the second picture and added some extra White at top of the head as well.
Plus changed the look of the mouth, still needs working on but onto other things at the moment.
Might come back and try again later in the week.
