When you finally finish the storyboard/animatic and it's revisions and it's now approved.

Another quick edit. I'm done.

I dunno man call this a parody layout of American comics or something

On the subject of Shirow and Otomo, I haven't started reading yet but here's a currently available book available right now in French that has similar visual vibes, called Great Trailers by Akira Miyagawa:

I just like manga with good pen texture and energy. Here's one I almost forgotten I had: Blue Heaven. It's a mini-series and I remember it being well-made. Murder mystery thriller on a ship. Was reminded by seeing Jumbo Max in bookstores. Wasn't as thrilling I must say :/
