Sometimes you have to experiment not only with geometry and material nodes, but also colouring. Here I've tried out a nice ocean shade of blue.
This is my latest 3D rigged Blender character, Joliette Fleurs. Her story: I found an AI render of a beautiful woman on some internet forum. I decided to create an entire character based on this. The AI steals from us? No problem! I steal back from the AI. Joliette Fleurs is the result.
Of course, I couldn't just stick to the reference material. She had platinum blonde hair in the reference AI render, but here I've decided to try ocean blue. I will probably redo this hair from scratch later, but it has been a good experiment so far.
