That you manage to get some subtle yet very there alliteration in a monostitch, well. Goodstuff :)
I like this, broken down, because:
- your soul is empty
- it used to be a refuge (maybe even holy)
-it is about to get dark (are you afraid of that?)
-someone haqs abandoned you/ or - you have been neglected
- the colour of sunset is stark and cruel next to your abandonment
and all that to say this: this one has layers, it's open yet focused, there is a lot in this line.
