Marina the Mermaid - Character design

These drawings belong to a character development that Penguin Randomhouse asked me to draw for a middle grade saga called “Marina the Mermaid”.
They asked me to draw: a color version, a two inks one and a few sketches about:
- Marina as a mermaid
- Marina as a human child
- A pet of my choice
- And I decided to draw a few concepts too (her bag and her magic cameo).
