Don't mix Karin brushmarkers with Pentel Stylus

I do some coloring with one of my most favorite art supplies ever, the Karin Brushmarkers PRO brush pens.

How the frog's stomach turned out to be wasn't intentional, but at least rest of the lineart didn't get as smudgy and it's not like it got ruined beyond saving. It's been ages since I've last used the Pentel Stylus pen, so I didn't remember it wasn't entirely water-proof lol. Not to mention that it was also slow to dry on a marker pad paper.
