My newest is finally finished : Steampunk Princess by La Fabrica Roja, (you can easily find them on facebook) and you can get one of these miniatures from CMON.
I did use the air brush on her for the flats of her skin and shirt since the areas were so large I didn't want the paint to build up and have her look lumpy. Other than the flat color everything is painted with a brush.
I plan on trying out the air brush more for painting since I've seen a few videos and tutorials on it and they make it look simple (*snort*). I have a ton of miniatures to practice on so we shall see how that goes.
I hope you enjoy my version of the Steampunk Princess as I really enjoyed painting her and can't wait to put her in my display cabinet.
