About those backgrounds, they are hand crafted or made with editing the screenshots of assest store. Real Clip studio subscription will definitely help. I don't have money for that. I will arrange that from somewhere.
Hai, wakatta. No worries. My first post (and even this one in parts) may come across like nitpicking, but I believe pointing out things I noticed is the appropriate thing to do if I'm going to give feedback. I look at your work and tell you my impressions and give my opinion. I do that because I really respect the effort you put in and seriously, I want to see you improve your skills with this project even further. The result will be more Sumire for us even if Kisa sets his focus on the school part.
One thing I like is the load of intro pages about the series' background. Compared to the original this approach feels good. Ah, but you might want to change "Satou House" to something like Satou family's home (or residence). That's my personal taste, but Satou House sounds a bit weird in my ears. As for the project as a whole. It looks like this will be cute and fun, so just keep the general direction, it's promising.
I like that final page with Sumire posting. Not sure if you will re-use that for all chapters. But the general idea to show how Sumire is posting about her daily life with Sou (which the others will call "delusions") is cool. Maybe for the next chapter that page could not have Sumire but one of the serie's characters reading Violet's blog - let's start with Akira, because she told Kana about it, so she was likely the first one. Akire looking at her tablet with a worried expression. Later it could be Miku (shivering on her bed like a junkie) or Kana grinning and drooling while looking at her Smartphone. Well, it depends on the content, but I think that would be quite funny.
By the way, when you told us about this, I was wondering if you would make it full color but it seems you decided to go mainly mono with colored pages mixed in (and the colored ones probably focussing Sumire). That's fine. But in this case, try making a unified, distinctive text coloring - it's even more important because colored text on mono pages will really stick out. Maybe upload your work in png format instead, if jpg creates unwanted artifacts.
Let me give a final comment on the color pages at the end, I think they are plenty cute and Sumire's goofy side comes across quite well here - though her facial expressions during the princess carry were even cuter. A little more nitpicking from my side, though: On P28 one of Sumire's nails got skin-colored by accident.
Now then, I'll leave it at that.
Thanks for sharing this ♥
