Ok, I'm not new to miniature painting. However, since I collect Necrons, I always paint with metallics and have had never to highlight. However, I want to know how to do it. I looked for various tutorials and they weren't really detailed enough. So if someone can give me a step by step tutorial (pictures would be good) or give me a link to one, that would be much appreciated.

Some of my questions include:

1. What does layering look like when it's halfway through?

2. When layering, do you paint the successive layers in the middle of the last layer of the edges or somehwere else?

Any advice is appreciated but ones directed towards Lizardmen even more so.
