Rapunzel Concept Art

Rapunzel concept art.
Another concept of mine from the Grimm brothers fairytale.

My idea is that Rapunzel is a precious substance that scientists decided to put to a cyborg/robot to feel emotions and interact like a human. The scientist is Dr. Gothel and she created Rapunzel in the memory of her dead daughter.
I decided to explore the hair and body details of Rapunzel on the concept sketch.
Also once, the concept for Rapunzel is done, the idea for Dr. Gothel is already clear in my head. So it's easy to draw Dr. Gothel to complement Rapunzel
