Hello!
Hate to break this to you, but you're more likely to be struck by lightning than to realistically expect anyone on Itch to drop $50 big ones on a random art book by a random author, featuring honestly less than stellar cover art and described on Amazon as a 'exegetical transliteration that continues my prior discussion of literary and art history.'
I don't know what brought you here, but itch.io just isn't the sort of place for this kind of work; I wish it were! To a modern savvy sarcastic Internet audience (/with near zero Media Literacy) such projects smell like effortlessly Pretentious™ andor Academic Postmodern Nonsense and feel borderline self-parodying. My humble suggestions:
1. Give me a free review copy, and I'll give you an honest critique. (I love these sort of books! I'm working on a 2M word one myself.)
2. At the very least: provide a short PDF Sample on your project page.
Sincerely
Robert What, Philosopher Consultant For Hire
