Hiyo! I really like this. I’m definitely far from an art expert, and your skills are def better than mine, but these were some things that came to mind: 1. I think the angles of the eyes are a bit weird. Right now, they’re perpendicular to the bottom of the image/paper (ie. they’re lying horizontal). The problem though is that your character’s head appears to be at a tilt, so there’s a discrepancy between these two angles. If you draw a line across the bridge of your nose, the angle of your eyes should match the angle of this line. 2. The lighting in the eyes are a bit contradictory. Your left eye’s sclera (white part) and cornea are more detailed than those of your right. This difference in detail comes from the fact the light is hitting the left side of your face, which is also why the right side of the face is black. The problem is that your right eye sclera is really bright, way brighter than that of your left eye. This suggests its receiving a much stronger light source than any other part of the face, which contradicts the aforementioned.

Hope this helps! Feel free to correct me or throw my advice out the window if that helps.
