>>112525117>>112525132There are two concepts in art that get conflated a lot: perspective and foreshortening. Perspective is when things closer to the camera are larger, but foreshortening is when a long thing pointed toward the camera looks shorter. For example, the attached image shows an arm pointed toward the camera. If you put a ruler up to your screen and measured how long each arm segment is, they'd be very short, but that's just because they're facing the camera.
A common amateur mistake is to have perspective without foreshortening. This is what you see in the OP's image: the outreached arm gets bigger along its length, but it's not actually any shorter.
