I paint this picture from my feelings when I read a book and got some comments from the previous post about how the character should look like.
She supported Zombut secretly without saying anything, She helps him truly from her heart. She doesn’t want anything back. She just want to see Zombut’s happiness. She sacrifice her life for him to live longer. She give him everything she can.
Her left part of the face is already rotted so she covered it with her hood. Her right part is going to rot so I paint it to capture the feel of losing her love. Her tear is actually her blood coming down on her cheek to her chin. It represents the painful love of hers. She still smiles with bloody tear because she is proud by helping Zombut. She reach her goal.
Edit: I changed some parts from the comments
