I was very into mythology years ago. One of the things that fascinated me for long was the different kinds of dragons and the specific features from each one.
Some months ago, this scene came to my mind: my very personal vision from a rainbow dragon and a red dragon. I started painting right away.
This one took me AGES!! Mostly because is huge as hell. You can see some details and some WIP steps here: [link]
