Hey there, I really like your drawing and character, I feel like it mostly looks alright already, but I can see the lighting issue you mentioned, I feel like most times theres a problem with the lighting is mainly due to not thinking enough about the planes of what's being lit and not have the adequate contrast, that's why I darkened the background, I also pushed back on that greenish secondary light and brought it back as a rim light. Made sure the volumes on the hair and eye socket read well, and some other smaller details. I hope the result is helpful enough to you. | Artwod Feedback
