Drawing Sasuke's Sharingan is one of those things that looks deceptively simple but has a lot of nuance if you want to get it right. First, start with the basic shape of the eye—Sasuke's has a sharp, slightly downturned outer corner, which gives him that intense look. The iris should be a deep red, and the Sharingan itself has three tomoe (those comma-like shapes) arranged symmetrically. I like to sketch them lightly in pencil first, making sure they curve naturally around the pupil. The key is to keep the tomoe balanced; if one is too thick or too thin, the whole thing feels off.
Once you’re happy with the sketch, ink it carefully. The tomoe should have a slight taper at the ends, almost like brushstrokes. For shading, I use a mix of dark reds and blacks to give the Sharingan that eerie, glowing effect. If you’re feeling fancy, add a tiny white highlight to the pupil to make it look reflective. It’s wild how much depth that little detail adds. Practice makes perfect—I must’ve drawn it a dozen times before I got the swirls just right.
