Yep completely understand ! Impure´s images was very low res, and its easy to see yours is very high res compared to his.
I do wonder how long it took you to make the above image?, and the next question is if more hours would help improve her even more ?, like fiddling with her skin tone, eyes, mouth and so on.
I'm just curious about the time you put into it. Since I do not have experience with 3D artwork.
Finding the right skin, making the shape, experimenting with different make-up... Depends on what pc you have. I have an old but powerful rig. Still takes time to render etc
