Hi!! I'm editing your beautiful painting on a rush before class, but I hope this is insightful enough! I'd primarily suggest prioritising the big picture: address your light sources precisely from the outset to not only efficiently set the mood, but also smoothly work your way around shapes. It is essential to develop a profound understanding of the forms that construct the piece. Overall, splendid work. I largely fine-tuned the facial expression through some quick adjustments. Yay!! Hope this helps :D -Yirudraws | Artwod Feedback
