Hello there! This looks quite cool! What I would do is push the lighting a little further, since the portrait looks a bit too dark overall. Emphasize the illuminated areas more, such as the nose, cheeks, eyelid, and a few ribbon-like locks of hair. :) On the other hand, to create better contrast, you can use the background light to add a rim light or illuminate the side of the character a little. This will add more contrast and visual appeal to the portrait. :) Hope this helps! | Artwod Feedback
