I'm "technically" supposed to be working, but I just had to quickly log in to say I MISSED YOU AND YOUR POETRY! (even though it's only been a little over a month or so, it's felt like longer)
I love the line of "semi hidden treasure" - it's sweet without sounding overly sappy or cliche.
You gave a tenderness and passion with the perfect balance of visuals, and that last line is even more romantic, being graced by moonlight. The use of "etched" worked well here!
In the second stanza, should shadow be plural?
I liked how this didn't continue for many more stanzas, not that it wouldn't be as lovely, but that you said what you wanted to say in a simple but profound way, not needing lots of similes or metaphors. It felt more like a quiet observation, a reverence.
