As I said before I'm quite a rookie when it comes to painting miniatures. I found this site that really helps, called http://www.how-to-paint-miniatures.com
Can't go wrong with that, eh? But actually, when you look around the internet, you'll come across thousands of people with thousands of different painting techniques, and some tips and tricks that contradict another's. There's no easy way around this, it's trial and error, and maybe one day you'll be the one that give tips and inspire rookies.
