Bogdan's Digital Art Official

Fantasy and comic book fans, I have a question for you. Ravok is going to be a big book. So far we are expecting to end up with 72 pages interiors in Bande Dessinée (approx A4) format. To accomodate fans of brutal, epic fantasy, who want to support this enormous project while avoiding shipping costs, we've been thinking about the possibility of a digital only crowdfunding campaign. This means the book will become available to backers in digital format as soon as it's completed. Is this something that would interest you? And if so, what would, to you, be a reasonable price for a digital book of this size? Just testing the waters. Thanks for your feedback, everyone!
