It's Princess Leia! I've been working on this model since the summer and I attached a work in progress picture.
For references, I looked at her hair from Endor and her general likeness from The Empire Strikes Back and Return of the Jedi. I also exaggerated the details in the 3D model so that they would show up in the final print. For better printing results, I recommend printing at a large size and a slow print speed. (180 mm scale and 20 mm/s)
For the post processing, I sprayed it lightly with sandable white primer. I then sanded it with 220 grit sandpaper. After sanding, I sprayed it again lightly with the white primer and sanded it again with the same grit. Lastly, I sprayed it with a water based polycrylic (clear gloss) for a hint of sheen.
For the rock cracks, I used the brushes supplied by Luis, https://cubebrush.co/luisarmstrong3d/products/zywuhq/rocks-cracks-brushes
Lastly, the first image is the printed version and the second one is the rendered version. If people want, I will post for free a brush I made for her braids using Zbrush.
May the force be with you.
