As for elven subraces, I still think Tolkien did it best. His sub-races or kindreds branched out from each other due to various factors, mostly based on their relationship and experience with Valinor. Not only is it aesthetically pleasing and imaginatively vivid, it is also organic, arising from the setting itself and its history. It also validates a range of "sub-races" -- it doesn't end up feeling heapish like D&D, but natural. Complex but not complicated. D&D's sub-races mostly just seem heaped upon each other. And, of course, it mirrors our own world, with different ethnicities branching off from each other, usually based on geography and migration.
As far as D&D is concerned, part of the problem may be the term "sub-race." People, kindred, or simply group might be better, and they probably should be specific to the world.
