Here's a 3 hour drawing of Haru and Legoshi having a moment. I just love this panel from volume 17. Great read - Beastars - go check it out. There's definitely mature content in there, you have been warned.
This was done with oil pastels in a technique known as Sgrafitto, as part of a 100 day challenge on Instagram. I scratched the black paint off with a chop stick. Worked like a treat, so I'm planning a bigger piece with that technique.
