Here's a 1 day illustration that I made as a test for a concept art role in a french video game company. It didn't bought me a ticket for an interview but I really enjoyed doing it. Especially because the plot was: "main tough female character in a cartoon pirate universe".
I even think about turning it into a low poly 3D scene that would be uploaded on Sketchfab ;)
This one was made in photoshop using the excellent plugin Lazy Nezumi Pro.
Feel free to grab it on your phone or tablet :)
