I'm still waiting to hear back from one more person, but 4/5 contacted say that Thursday works well, so I'm making the decision in advance to choose that date.
So yeah! Stream will be on my tigerdile, starting a little after 5pm EST. I can't say for sure how long each sketch will take me, but I anticipate 1 hour per sketch, so here's the rough outline of when I think I'll be working on who's pic:
X_25 @5:30pm
Taki @6:30pm
Break for 15 minutes
Serval @7:45pm
Artica @8:45pm
Kardas @9:45pm (?)
I'll be doing another bottomless stream next week as well. I think I might make Thursday my stream sketch night, because it turns out Sundays are not as good for me as I originally thought.
