I wrote a small guide for painting figures with humbrol and oil colors.
I'm not the best painter (quite q beginner actually
), but the method gives nice results, and you can master it quite quickly.
the only problem is that its in hebrew, although there are many photos.
you can find it here: (the colors are humbrol, games workshop and oil, and their names are in english).
