Because there was no Moleskine Exchange in ages, I joined a few groups on Facebook that gives a weekly, a daily or a bi-weekly creative challenge, and people draw or paint according to specific prompt. Steve was one of my favorite participant in a group called Daily Drawing Challenge, in which a guy post a daily photograph and everyone use that as a reference. I quit that group pretty shortly after, because the lack of diversity in the images was pretty depressing, but me and Steve became Facebook buddies and we both do a lot of those group challenges.
So in Steve's book, all the drawings were results of some challenge or another. Also, just because I have an easier time working with a topic, this one became "Circus"
The one on the right was for a different group called Daily Spitpaint, each day they give 4 topics and people choose one and draw it in 30 minutes or less, that's the only limitation. The topic here was "Lion Den".
I don't do all the groups challenges everyday, but I try to get at least one everyday, it's a really good way to get me drawing. I highly recommend it!
