Good to know somebody else had this happen to them, and I'm not just completely mad x') Your pages look rather crisp to me as well. When I first started uploading pages to Tapas, I also had this feeling like the pages were significantly hazier than originally intended, but nobody else seems to have noticed- yet?
I can't help but wonder if this is just another one of those artist things where we've both stared at our own work for too long and the slightest thing reads as a "mistake", even though nobody else would notice.
