Ira Sluyterman van Langeweyde aka Iraville now has her artbook up on Kickstarter. It's called Cozy Days: The Art of Iraville and it's going to be published by 3dtotal.
The campaign is already a success with 992 backers at the time I'm writing this. If you want an early copy when the book is out, you can pre-order one at http://kck.st/2KLZC4Z
Campaign ends 8 June 2018.
