I'm assuming it is quite nice, but terrible adverts popping up all over the place and distracting from the overall experience, so I only skimmed through it before I closed the window (on a work computer hence no adblock!)
Here's something similar from The Guardian, but without the ads:
I'm looking through https://www.c82.net/naturalists-library/illustrations and all the illustrations seems to be of non-dissected animals/insects, at the illustration themselves. Of course, impossible to know if the illustration was drawn from a dead or alive specimen, but none of them seems based on anything picked apart as far as I can tell.
More at https://www.c82.net/blog/making-of-naturalists-library, you can see that the source material was actually in pretty good condition, just aged and yellowed; they used Photoshop's AI to stitch drawings that were spread out over two pages together. And probably some upscaling.
I took that to mean filling in the gaps on the source data, not literally filling in pen and ink gaps in the drawing. If so, that's a shame. It pollutes the original and isn't what counts as restoration.
Remember when it was totally controversial that Ted Turner intended to colorize classic films such as Casablanca, and how technology was going to ruin artistry in this way? Good times.
I don't like most of the colourisations of old films. I try and seek out the black and white versions when I can. B&W is a different medium from colour.

As an example, all the drawn butterflies seems to be drawn as if they were alive, not dead (https://www.emilydamstra.com/please-enough-dead-butterflies/).
I think that's clear
