I think it looks fine except it's missing a more obvious hint that there's more to see when I scroll. The one that's there is just textual and very delayed.

Not sure if I second this or not. I did want to scroll, but I don't know how much of that was influenced from the context or the extreme minimalism making me want to look for more - I'm interested in how I would have reacted to the site not knowing it had scroll fade. I could see an argument with the "Don't Make Me Think" principle.
