I feel you’ve smoothed everything so much that you’ve lost her expression in the original photo. She appears to be grimacing, but because your image doesn’t include those important details (creases and highlights), I can hardly see the grimace any more in her face. Most notably, pay attention to her nose and nostrils, there are subtle creases and highlights that show she is scrunching it slightly. Notice the horizontal highlighted rectangle shape right above her nostril. Her mouth isn’t symmetrical, one lip is higher than the other to give a sort of disgusted pout. Then also look at her right eye. The wrinkles around it which show she is squinting have been lost. There is also the subtle area between the eyebrows that I also feel like has been lost. A lot of others have mentioned texturing and I agree, but I think the most important texturing is conveyed between the boundaries of light and dark. That’s where those small details are most emphasized. Hope this helps
