Oya, I eventually managed to finish this page.
For some reason, while drawing it, I was often feeling like something was a bit off with the quality and kept redrawing some details. Bad idea, in the end I had to clean it because there was too much things. Good bye, dear lost time ;_;. But I won't do it again, so it's still a process improvement for future pages >:!Page 1Page 2Page 3Page 4Page 5 - here
