I love using a Japanese bamboo brush and black ink to f$*k around on sketch pads. Clears my head. Try doing single stroke or as few strokes as possible to get results.
Here’s a sketch I did as a kid. wonder what locale I was thinking of when I did it. 🤔 I remember a female artist I met in my neighborhood taught me how to sketch palm trees. So maybe I was practicing. 🤷🏻♀️ but I feel like there must be a pirate sketch as a follow up somewhere lol
