Love watching you work. I especially loved watching you draw and redraw the horns until you were happy with them. Let's me know I'm not crazy when I erase and redraw things over and over again until I'm happy with it. Just subscribed and can't wait to see more.
The staedler sizes I mainly use are 005 01 and 03. I use the ink the brush pen comes with. You can buy a converter and put your own ink in them. I choose not to, I'm fine with the ink they have. I assume its india ink.
