Here's my re-do of the first page. It should be around this level of clean or higher (like having the black parts painted black too, depending on your standards), while the grainy particles have to be erased, but not erasing any part of the real linework/shading.
I would do the cleaning too, but I'm not crazy enough to do TL + cleaning + typsetting all by myself. Then again, I could, but it will take me a lot of time just to clean up the pages.
Anyways, you probably don't have to upload the 2nd one. Judging by your first one, we're mostly on the same boat in terms of translating, just that you need to work on the English phrasing better.
