Thanks Ronnie! Well there is but...originally the boy's drone was going to have a dragon chassis, and I made an image brush to paint on the scales, but it looked a bit wrong cos I couldn't work out how to get the scales to taper with perspective, like on a gradient on an image brush ( cos I think maybe a few kids would love to ride their own dragon drone ). So will revisit when I learn more about AD, and see what's behind the portal. For now though, am working on a wee fantasy story with a little disabled girl, and would like to be able to illustrate it, but that is a few months away while I learn this marvellous app, and practice with some other ideas.
