Ohhh...such a beautiful and breezy image this poem has given me...love it! I especially liked this part:

Curtains flying

away with

charcoal shadows,

and of course the ending closes with a soft touch..enjoyed the read!

That was beautifully romantic... well, in a creepy way.
I love curtains that wave with the wind, this image can make me write long love novels for good.

Keep writing and versifying such images. So you.

Very clever, shows a great eye for detail, and a power to put that fine detail into words.

love the shape BTW
