Ah yes. Zhongli looking at the artifacts and childe looking at his bf, both saying "beautiful" but directed at completely different things.

Here's another idea tho, zhongli paints childe. It's a soft moment. Zhongli has to keep telling his bf to sit still but childe literally cannot because
1) his back is starting to hurt
2) he can't keep the same expression on his face because zhongli looks so gorgeous while being in work mode and he can't help but admire his painter.

On the other hand, photographer zhongli and model childe. HEHEHEHEHEHEHEHEHEHEH
