Look straight into a mirror with your face relaxed. Notice whether the crease is visible, where the outer corner sits, and whether the iris touches the upper and lower lids.
Hooded eyes often benefit from airy lift through the center and outer third. Round eyes can be balanced with a gentle outer flare. Almond eyes can move between natural, doll-eye, and cat-eye maps with very little adjustment.
The best map is the one that supports your natural structure. Treat these guidelines as a starting point, then adjust length and density until the eye still looks like yours.
