Thanks.
That does work that way yes.
But I've found the method I used in that tutorial useful, accurate and quite good, before my heads weren't too accurate to photographic reference images, but this one is, also the same principles can be applied to high poly. Which is why I've decided to acquire this technique.
For those interested in the source of that technique, there is a very good video demonstration of it at Kurv Studios, its a video with no sound where you just watch the model be made.
