Wow. I had (just now) made one comment on the bad layout. As you might guess, I'm on desktop, and looking at the site in a window wider than it is tall. I saw your comment and shrunk my window to be half as wide as it is tall, and the layout corrects itself and changes -- dramatically.
Surprisingly, I had the art exhibit impression opening it on 16:9 desktop. It's sparse, as a gallery, or a luxury boutique, where free space accentuates value of content. It looks OK on mobile, but on desktop it's the sparse, but non-monotonous layout, that guides attention and provides a second layer to the content.
