idk if more eye detail is the fix, maybe place a simple box around each eye first and check the top and bottom edges as the head turns, then add one clear highlight shape so it stays in the same perspective.
Mastering to design in anime stylish eyes but always feel missing
Artist's notes:
In this image I try to many variation and trying to improve my eye design and actually I develop my art style without no realisation after the realise I still struggle something in drawing highlight and drawing any thing in perspective and angle is my struggling problem and I am most of the bad drawing noes That's why I decide to share my problems I need a feedback who give me around this topic
