Here is Ant-Man Sketch Cover painting process 2. Started the metal painting stage. This stage is achieved with dry brush layering. Going back and forth with adding the darks and lights. The brushes I use for this stage are the size 5 & 10 spotter, size 2 angled and chiseled blender. The reason I use dry dry brush technique is it picks up the grain of the paper and you get these subtle imperfections that add value to the overall feeling of the artwork.
