Does her right leg below the knee down look really long? Or is it fine?
It looks right on normal anatomy for the leg part, but for the whole picture the legs are far too long compared to the torso. The problem with this picture is the hip area was concealed by the skirt so you can't see the attachment point to the waist, thus giving the illusion of longer legs. Normally your femur : tibula and fibia bones should be around 1:1 ratio, which is easiest to observe if you're squatting, but in this case the smoke covering the ankle part of the boots kinda skews with perspective.
