For a webpage [0] about visual art, the art itself disappointly gets less than 5% of screen space. When you present art you're supposed to present the art. This page is a massive waste of empty space, asking the viewer to employ a magnifying glass to see the thing being talked about.
Here's a quick mockup of how I'd do it:

The gallery page [1] doesn't even work. Clicking on an orb just makes it black, nothing happens.
