Blob Game drawings. I play with stupid rules, tbh. First of all, I start with really complicated shapes. Then, when looking at the shapes I'm not allowed to make it into a drawing of a man with a large nose, funny mustache, or goofy hat. I feel like that forces you to be more creative, but sometimes it feels almost impossible to find stuff in the shapes.
I used Poscas to make the shapes, and then used either a Pentel Hybrid Technica or a Pilot G-Tec-C. I think. Not entirely certain if the Pentel Hybrid Technica was the thicker pen, but Pilot G-Tec-C is definitely the thinner one.
