Marc from audioattack asked me this question.
At the very beginning it was like that, I don't remember exactly - I think version 1.0 had 46 acrylic images and they were only from F-Droid. But then I also added app icons from the IzzyOnDroid F-Droid repo. On the one hand, I was then no longer so ‘limited’, on the other hand I could show new acrylic images or only change them again. That's actually easier if you have the time for it.
Perhaps your question was also intended to ask me to draw app icons from other F-Droid repos and then programme them into the icon pack. For example, Molly, which is only available in the in-house Molly F-Droid repo. I have my collected list online on F-Droid Family (1).
Of course, I could also add more F-Droid repos for the icon pack. But then the other display errors would remain. Although I have to say: When I created the last version, everything was still displayed correctly. However, the package names can also change and not all of them are displayed anymore.
Friendica from the Friendica repo and Bitwarden from the saunarepo display my acrylic paintings. For more you are welcome to help me.
