It seems to be work-at-your-own-pace, at least I know I won't be able to keep up every single day. The first assignment was a pen drawing of a still life set up of stuff you find around you.
Drawing right with pen is harder than it seems. I was so worried about drawing a line wrong it was hard to loosen up. I pretty much always use a pencil first when drawing, so I feel a bit more free with my lines, knowing that I can erase.
