Heterochromia
Heterochromia is arguably one of the most iconic visual elements of anime character design. As you can see, it is usually used to signify that the character has two sides to themselves, a special power, or is just generally an eye-catching design that sets them apart from other characters. It is that striking contrast of color that fans seem to enjoy when it comes to customizing their own versions of this artwork.
The artwork is typically designed to be quite detailed, especially when it comes to close-ups, to make that gaze as impactful as possible. It seems to be a work of solid quality, especially when it comes to that high-resolution portrait of the character that fans could set as their phone background.
