I’ve added a few more figures to my illustration of constructing defensive earthworks at Sandal Castle and now I’m adding flat colours, using a vector brush in Adobe Fresco and the paint-bucket tool to fill in larger areas. I can see why people find colouring relaxing.
I was going to go for red for the cavalier directing operations but I discovered that Cromwell’s New Model Army was issued with red shirts, so I’ve gone for blue instead.
