Maybe you could try to use oof glasses/bottles or something with sparkle, but then oof stuff probably isn't what clients really want to pay you to give them; I'd thought of those napkin-art works some restaurants delight in offering you - those things you fear opening out in case you cut your wrist on them or, worse, remove an eye. But nothing, really that demands the human presence too close to camera. Your people are just at the right distance to give scale.
Oh the (relative) joy of unpaid work!
