Thank you! This is great feedback. The filters are lower contrast because we want the attention to stay on the art. But they might be too low-contrast and introduce usability problems.

We love sculpture and we're really excited to have it on the site. Sculpture is tricky, though, because shipping is usually more expensive and it's trickier to pack sculptures in a way that keeps them safe. That said, we're gradually rolling it out. We have a tiny number of sculptures on the site right now and we're going to add more as we get more confident in shipping them.
