The teachers are apparently mostly freelance illustrators and artists. I have come across some of them in other places and am confident that they have something valuable to teach. There seems to be stuff that is nice to have, like ideas and tips for illustrated journaling, but also videos that teach techniques like pen and ink drawing.
I started yesterday with a nice botanical line drawing course and made the following double spread.
But I soon want to try out some more sophisticated stuff, so I can see if this place is worth paying for. Stay tuned.
