Look at those muscles! (Patreon)

This is a small anxiety-release sketch I did while attending Uni courses. Drawing helps me a lot to concentrate ^^

The dragon isn't a specific character, I love drawing random stuff since I don't have to stay "on model". I like to imagine this dragon as a marine creature with retractable gills under covering hard plates but also able to breathe air through its nostrils.
The first inspiration were armored fishes, I really love them.
