A lovely write, I like the symbolism gently woven throughout this. The ending is a bit harsh and abrupt, but not inappropriate; so is death.
The only thing that puzzles me is how you chose when to punctuate and when to not. Its becomes the age old debate over whether its artistic of just laziness. I understand why the ones that have it need it, but would I like it better fully punctuated? I'm not sure. Its becoming a preference thing.
Overall, I feel like there is very little critique with your work. You have definitely thought through this piece and crafted it well.
Ah yes, to be the shade in someone's shadow. Silhouette sojourn taciturn. My mother died recently so I can relate to this very well. She was an artist, a musician, and also held a degree in interior decorating, an amazing woman I will never forget!
This is a lovely tribute. Do I understand from it that your mom has died or is it a fantasy. If the former, my condolences.
