The problem I have with all these Halfling designs, is that it still feels like we're designing midgets, like these were humans who just didn't develop properly. I don't really like that concept, it breeds a far too humano-centric fantasy for my tastes. Elves don't look like humans with too little meat on their bones. Dwarves don't look like humans with too much. Halflings don't even look like children, they look like improperly proportioned humans, even in the latter renderings...which are better than the initial one, but it still feels like they're holding to some idea that halflings resemble midgets.
I've never pictures halflings like midgets, they're just generally small humans. Fully developed...just proportionally smaller.
Sure, I've complained that too many races look like just "short humans", "fat humans", "skinny humans", but I don't think altering their proportions will do anything for that.
