Magnificent! I had long wanted to commemorate rusalki but you have done it so much better than I could hope to I feel satisfied with your work.
You might find great joy in the Rusalka trilogy by C. J. Cherryh.
I think you have the seasons wrong in this poem, you contradict yourself in nearly every line if it’s Sludgy it’s not green. you say the morning then you talk about it being dark! and then you talk about the marshes come on mate you’re good at criticising other peoples work look at your own. ????part from That you have an imagination
It feels like you were looking for things to criticise here. I didn’t once say it was morning. I compared her song with a morning bird. :) with regards to the vocabulary used, I don’t understand how greens and browns are impossible colours given the setting? There are differences between swamps, bogs, marshes, I know. I simply used them here as synonyms. The reader isn’t stupid - they can imagine this scene pretty well.
There’s a difference between constructive criticism and this comment, I hope you realise.
