Help - is this impossible?

I am trying to photograph an artwork that's comprised of strings and wax beads - My boss keeps saying the image "isn't sharp enough," saying that when he zooms into the image he can barely make out beads.

However, I don't think it's possible to focus on every single bead. He has zero photography background (to be fair I barely have one either) and says "it's simple, there must be a camera setting that does it."
