a new model from Topaz just dropped a few days ago called 
Starlight Precise
And i have been doing some limited testing on it and its quite a bit better than the previous versions in certain aspects, but slightly worse on others, this model needs a higher quality original version to stand out, so the plan is to use the old model to bring it up to a certain level of detail and then use this model to fine tune... (i still have to compress these files since my upload speeds are atrocious on this site)

Nice work, but one thing I notice is the tendency of AI to 'recreate' the image. For example if you pause both videos at 8 seconds, in the original you can read the bottle: "Old man's". But in the enhanced version you can't read it. Her face has also changed. I've seen pictures of this model, and in the enhanced version she doesn't quite look like herself.
