I hate the short, cute christmas or keebler version of elves! Why did that persona ever come about. If anything that is a gnome!
Anyway, the general fantasy version of an elf is:
Elves tend to be somewhat shorter and slimmer than normal humans. Their features are finely chiseled and delicate, and they speak in melodic tones. They concern themselves with natural beauty and are known to dance and frolic. They are not particularly fond of Humans or Dwarves and they do not have a strong interest in wealth. Although they appear fragile and weak, as a race they are quick and strong. Elves often live as long as 1200 years.
Yeah, thats from BG because I am lazy and just pasted it.

Can an elf get a break anywhere these days?
