So what I'm looking for is a more original design, particularly for the nymphs that supposedly live on the tropical islands off the coast of Hammerfell. I do suppose there are other nymphs in other places, and from Greek mythology we know that there are many different types http://ancienthistory.about.com/od/godsandgoddesses/a/Nymphs.htm. Also worthy of note are the Spriggans, which we have seen in two prior games already and may provide some inspiration as to what nymphs could possibly be like in the Elder Scrolls world. Not that I want to see an ugly nymph (almost an oxymoron?) but doing something in a new way will be rewarding. I thought about, for example, a nymph design that draws inspiration from the jellyfish family (and perhaps other underwater invertebrates).
But really, you're drawing it so feel free to go any direction you want with this, should you be interested in drawing! Hell, with all the interest in Skyrim, maybe a nymph from that province would be cool? Assuming Spriggans don't dominate the place completely.
I'm an awful artist, but give me some time and I might put something up. Just wanted to get this topic in on the weekend, should it be Monday before I have anything worth posting.
