>>2722997There's a subtlety in the curvature of the soles of a foot that can be hard to pin down. You see it with hands too. Palms never look quite right a lot of the time. But anime in particular runs into two problems more often than not. They'll draw toes like fingers which makes them clawlike and they underestimate the foot's overall length. A person's foot is about as long as their elbow to their wrist. Anime is notorious for making them way too tiny which makes them look poorly proportioned.
