I don't usually post lineart but I really wanted to share this and I may start posting lineart in the future too.

'Tis the one, the only, Kaneki Ken! Which I will color later (I drew it tradtionally but I'm coloring it digitally, so hopefully I won't screw it up).

Before you look at the reference I want to say that 1. They look way different because I wanted to look at something for the general shape but at the same time I also wanted to change it with my own style and make it look original. Also, I drew Kaneki not Sasaki.
2. The reference is from Tokyo Ghoul:re (chapter 7), so if you're not at least that far in the story and are planning to read this awesome manga in the future then maybe you won't want to look at it. I don't know if it would be that big of a spoiler but ..... just in case....
