[@Antarctic Termite] I'd say that's distant enough from Tolkien elves to be tolerable. My beef with them, particularly when they're xeroxed into other fantasy settings, is fourfold:

[hider=Muttonrant]
- There are always half-breeds with humans specifically and no other races (except sometimes with underdeveloped lip service) and there are no medical complications from it.
- Their writers seem to gloss over the idea that a century-long childhood period is developmentally messed up in terms of life experience and this is never addressed. The best they can do is address some of the issues with living so long. And again, this is mostly underdeveloped lip service.
- They are the original high fantasy Mary Sues. This is rarely, if ever, addressed.
- YES LEGOLAS, YOU LEFT YOUR FUCKING HAIR STRAIGHTENER ON, YOU USE IT EVERY HOUR! HAVE YOU EVER CONSIDERED SHAKING THINGS UP FOR ONCE AND PERMING IT INTO AN AFRO, YOU UNCREATIVE TWAT!?! WHY DOES EVERY ONE OF YOU PANTENE-ABUSING ARCHERY NERDS HAVE THE SAME HAIR STYLE!?!

Tolkien got away with the worst of this crap because he made elves in the context of his world (apart from the hair). People copying him too often fail the step where they actually make sense in the worlds they create.

As for what you suggest, Termite, obsessive anorexic hypersensitive reeeeeee-screamers with a regular mortal lifespan work just fine for me, especially if it was on Galbar. They would just need some means of not getting eaten.
