I'm not drawing much traditionally right now but I def want to get back into it more seriously. I've always preferred working in a standard HB pencil but lately I find I prefer to go straight through to pen which is usually whichever biro I find laying around on the computer desk.
I mainly use traditional for practice whilst I'm working on getting my traditional equal to my digital ability and I find if I'm drawing with pen straight up it forces me to learn where my errors are because I can't change it.
I'm interested in picking up markers at some point!
Edit: a video I just saw reminded me I'm also interested in trying clay at some point, I've always wanted to make 3D busts of my characters!
