95%+ images are scraped from dic.nicovideo.jp.
That's AFAIK the most complete source of this artist works.
Notably it included unfinished/WIP works.
(but I did have to go through the boards to find them since they are missing from the artist page)

Pixiv and seiga had a few images not present on dic.nicovideo.
Most notably a few Pixiv versions have a bit higher resolution.

I did verify there are no duplicates based on the pixel-data checksum and later manually but there may be
a few I missed.

I am missing most of the images used in this:

Only the one used in the beginning is here for now:

Let me know if you happen to find the rest.
