I finally finished all concept art for my 18+ doujin The Secret Name a couple days ago. Here are a few pieces I'm willing to share. :) I will now be working on the thumbnails. I don't know when I'll finish this comic and I don't want to make any promises on a release date, but I'm working hard on it every week. 😊
Here's an in-depth write-up on my blog about each concept art piece: https://reizako.com/blog/the-secret-name-concept-art-finished/
