I included these two facial expressions cause at first I couldn't decide which one is better and more natural.

Eventually, I settled on this one. Then I decided to work in the shadows.

Here, I added flat colors. In this video you can see some of my process for the later stages in adding more depth and highlights.

For this last rendition, I felt like the lighting wasn't popping enough so I added more shadow or darks. And I added a couple more accessories to give her more personality. Also, I felt like there wasn't enough of glow and shine to bring the gold accessories to life. I don't feel like this is quite done yet. I'd like to give her more tattoos and adjust the lighting on her hair. And quite possibly, a couple more accessories. I would also like to work on illustrating her in different poses to get a better feel for her character. If you have any suggestions or recommendations, please let me know!
