I think if I were to write nymphs....hmm. My dryads would be eco-terrorists who are only getting along for the sake of the forest. Normally, they don't like each other that much, as trees do not get along (and try and sabotage and/or directly kill each other - seriously, watch David Attenborough's Life of Plants),and thus the gatherings of singing and dancing that people have witness throughout the ages have either been war councils, or actual war. They'd have names like "Tallest-Ash-In-Glade" and "Oldest-Oak-Split-In-Two-By-Storm" and "Vine-Fig-Who-Strangled-Three-Trees", and not be interested in sex or romance, because they are the spirits of trees.
(Never trust an oak dryad - they are patient and crafty, and know that generally they just have to wait for everyone else to die before they are able to rule their part of the forest).
But I like twisting tropes, and running with things, and making non-human humanoids as non-human as I can. You could do some really fun things with nymphs, I suspect.
