If you're really into getting your minis looking as good as possible, you'll want to take every opportunity to improve your skills. My skills are incredibly lacking, with my painted minis just north of "well, they don't look like you did it with a paintball gun..." So if you don't want your painting to be like mine, you might want to sign up for SeminART 3 with Chris Clayton.
The fellows over at Figure Painter Magazine do their best to give you everything you need to up your painting game. But different people learn in different ways and having an instructor actually show you techniques first-hand is a great way to get better. Well, with that in mind, they've started their SeminART series of classes, the first of which is booking now.
