This image started out as me wanting do a character design of an evil wizard and then grew into him having a pet dragon. I wanted to do something similar to the wizard from a very cool lego set that actually comes with a lego dragon as well.
(The beard is probably my favorite part)
The drawing was done on my iPad using Procreate. It is incredibly easy to import images from that app into photoshop where I do the painting. As I start the painting I will usually do a few multiply layers to build up the values and start the colors and then do some overlay layers for highlights and making certain areas brighter.
