Hah- if there was a simple answer for that, we'd all be doing perfect 3/4s Measurements aren't a huge problem- its the shape that gets you.
If you can think of the nose as a 3d shape, the eye begins right above where the wing of the nostril would end. Its Kind of hard for me to explain... My suggestion is refering to pictures of people doing a 3/4 turn insteed of learning without a true referance.
Concentrate on getting the front right. I didn't get beter at 3/4 til I solidified the front. Once you get that, then you can invision it easier on an angle Unfortunatly, there is no short cuts with get art *right* Just advise. The best way of learning is giving it a go, and learning the correct way.
*sigh* I suppose your right, I just think people look more interesting from the 3/4 veiw. Practice, practice, practice though and I'll get to it eventually
