Good start Jay and nice figures to begin with, I'm pleased you're giving them a try.
Great tips from Ed. A little variation on Don's tip is to leave one of your painting lights on and point it at the figure from your imaginary light source, for example top left and take your photo with your camera set to black & white, you get an even better idea of where your high's and lows will be.
Keep it up Jay, quite a few people are put off flats at their first try and give up but it really starts to come together with practice.
Roger.
