Here you can see the original sketch design idea for Eterna. I wanted to encorporate fractals into her design somehow as I know that a lot of meida like to interpret time as fractal corridors in space. My main idea was that most of the fractal imagery will be on her dress though I did think to have her hair be fractals (an idea that stayed for a long time)
I eventually cleaned up the face area and outline of her body and thats where things got interesting. I made a custome brush based off the outline of her dress (everything below the waist) and then went mad with the brush. Mixing it with black and white. Eventually i then added more of the fractal imagery that were coming from her arms to her dress to create a focal point. It shows that these patterns branch off of her into a potential infinity. I also refined the fractal belt she wore around her waist, blackened her chest to create a contrast to the white area around her face.
I then eventually refined what the fractal design was on her belt and replaced the old version of it. I then also overlayed a much larger version of it over the general image to help sell the fractal themes. The edges of her dress were then made to fade to white to draw more attention to her face (and how things lead to infinity) then simplified her hair as i felt it was removing too much attention from her face.
