I'll call it finished. I could have tweaked it forever but it's time to move on to other things. Thank you very much to everyone for the earlier feedback. I've entered it for consideration to be printed in Expose 7 and I'll let you know if I hear back.
The characters are naiads, the fresh water sisters to nymphs. I wanted them young and beautiful but also give a subtle dark undertone. Unlike nymphs who were by and large altruistic creatures, naiads were just as likely to drown you as help you.
