Super minor thing, at least outwardly, but I was reading through some stuff while shopping for concepts and noticed that Valenar elves replace the typical Elven weapon proficiency in the longbow, longsword, rapier, and shortbow with proficiency in the shortbow, scimitar, and double-scimitar (source: Races of Eberron page 81). That would be neat to have, since the weapons are pretty iconic for their culture.
