Hey ccstat,
Sorry, I didn't see this thread until today!
We've definitely asked our illustrators/artists to go and tell everyone they know about the art book specifically! We did end up making a couple of art-heavy tiers, btw. We included a digital download of the album in the tiers, because the main focus of the campaign is the music. Though, if anyone does just want the art book, they could back at the $5 tier and add on anything they want.
The art book will have a lot of what would end up in the Kickstarter edition CD (if that gets funded), but it will also have much more, including a number of new commissions.
I'd personally love to have you in the Wandersail choir - that's one that I'm most looking forward to! Time commitment isn't huge. And the turnaround will be something like 3-4 weeks. I'm looking to give a few different options, depending on how big the choir is. The main one I'll be sending won't be terribly complex, but it'll be fun!
All great questions - and don't hesitate to ask any more!
Michael
