I feel this. The shading on the legs and details on the clothing on the right image is much better, but the face and eyes, and even the shape and style of the hair on the left image are more appealing to me. She went from the classic 'strong silent' trope look to a more 'shy bashful' trope look.
Also, she appears to have had a career change lol. Left image you can see an apron of sorts behind the bottom of the skirt and see the classic top of it on her backside. Neither are there in the right image, so she became a schoolgirl suddenly?
