It is totally looking like her. The first thing that comes to my mind is that maybe you’re having trouble noticing the likeness because things like the hair makes a huge difference. So maybe you either try to get her bald in the pictures so it look more like your model or you add hair to your model so it is easier to her looking like in the pictures.
Super tiny details makes such a huge difference when it come to likeness. Doing humans in 3D is the hardest challenge there is, so you’re playing the video game in ultra hard, you’re fighting Thanos without all the other Avengers, you’re climbing Everest without oxygen, so it’ll time a lot of time and practice. I have heard Kent saying that you’re not going to do it in one go. You have to finish your model to the best of your abilities and then try again from the start and each time you’ll get that one extra experience point for you to level up and before you realize, one little XP at a time, you’ll go from level 5 to level 100. It’s all time and practice.
