At least sort them all out. Like, Parody per Parody, Character by Character.
Your volume 3 gallery was a bit better, though Shielder kept having her own "Chapter" vs the other characters in the gallery.
Here you've got the fate/grand order girls, mostly Shielder then 1 Ishtar, a few Scathach and Sakura Matou. Was going to make a list of pages for each character, but its very difficult.
