I've been painting on LiveStream a lot over the past few weeks, all be it a little sporadically. I've compiled a short LiveStream page, with fun things like the LiveStream F.A.Q, and links to saved sessions, etc! Check it out at:
If you want to catch a live session, there are a couple of places you can keep an eye out:
Follow @screwbald on Twitter to be notified every time I'm painting on LiveStream, for all projects, or...
Follow @nordguard on Twitter for less frequent notifications, pertaining only to comic stuff.
You can also follow on FaceBook for updates!
