When I got back into painting a few months ago, I picked up Reaper\'s Learn to Paint Kits, and they help you learn basic techniques pretty well.

I would probably skip kit #1, and go right for #2 (skin and cloth), #3 (nmm), and #4 (advanced skintones). I hear that they are in the process of rewriting the guides though, so you may want to hold off a month or two. Also they replaced the old paints in the kits, to the newer master series paints, so if you buy them at your LGS, make sure they have the sticker that says \"new master paints\" or just order from reaper direct.
