I started this a week or so ago but it still needs a bit of tweaking.
The folks over on the Drawing Board have given me some helpful pointers so hopefully it'll help with the likeness a bit more.......
Just for the record, this is how I actually wanted it to look. I kind of cheated by doing this but for the benefit of the purists out there, I'll be re-drawing it from scratch to get it right.
Here's another update, As you can see, I've gone against my better judgement and decided to stick with the original shaped face.
