Maybe it's because I'm used to working with sketches and reconstructions for unidentified decedents, but I don't find the two versions that terribly different. Sketches like this are always approximations, not portraits. The suspect could be anywhere from 18 to 40, with quite a range of possible height and weight. The two sketches present a range of possible appearances. The real person is probably somewhere in between.
Here's a good article about it:
Facial reconstructions help identify murder victims. The forensic artist says, "As a forensic artist, I live in a wonderful world where "almost" is good enough," Mullins said. "If somebody sees an image that
kind of looks like someone they haven't seen in a long time and it sparks that recognition, we've done our job successfully."
