There a some changes made that I knew I would just have to get used to since they are artistic changes and not the fault of lighting or broken textures.
The skin in direct lighting is much, much better. In shadow, it reverts to the waxy look I'm not fond of. With the updated lighting, my character now has a slimming effect on her cheeks and chin, eye bags, and a more youthful look. Not happy about her looking younger, but it is what it is.
For things that weren't a lighting issue such as the corners of the lips being straightened instead of a small smile, larger pupils, droopy eyelashes (outer corners of the eyes are "pinched in"), and dimmed limbal rings in bright lighting (in night lighting they glow)—I had hoped this would be changed since, although small differences, it changes the expression of the character.
There is also the separate issue of missing scales on face#1:
And another issue when zoomed out the head base can be seen through the hair:

Overall, I'm not completely dissatisfied, but also not as happy as I hoped to be. I know I'm probably just being nip-picky, but I've been staring at this character for 8 years, so it'll take me a bit to adjust to her updated look.
