I just discovered the work of Olivier Leger. Awesome combination between art and marine conservation!

Using digital art, in particular Krita.
This is a hand-drawn reproduction I made of a drawing by the French painter Bernard During.
Here you can find a nice article about Bernard Durin. I recommend looking through some of his amazing work :)
I keep learning with every drawing I make!
