Hey Baz, loggie is referring to the zygomatic bone, and I actually prefer to cross over the loops over the bridge of the nose/nasal region myself. It helps a lot with expressions. Any muscle movement of the cheeks no matter how slight will have an effect on the softer bits of the nasal region anyway so... I'm down with that :) Prolly the next task would be to get enough polys in the nose area to begin to shape the wing of your nose. Here's a rather odd expression I quickly sketched to demonstrate how your setup can help with this... Bone loops are the basis for your shape and muscle placement, I have a bad habit of skipping them over since I already know where to place them. Exactly like drawing or sculpting, I tend to whack down the volume then start detailing it from there. Again this is a bad habit...  You already have the basics down, now detail the heck out of it!
