Yeah, I gotta admit, I don't like the 5e art for halflings. Weird is the right word. But, I get why they went that way - at least it's an attempt to make them recognizable.Actually, I agree with @Hussar on this one.
Well, I do in some ways. Firstly, I would prefer it if halflings did not have odd and frightening proportions, but, without a distinct culture of some sort, halflings really are absolutely pointless in that they are more 'human' than any other humanoid race (other than humans, but that's a given).
Large feet, covered in hair, and oversized facial features are fine, but xenomorph heads and spindly limbs are... in my humble opinion, a tad weird.
One of the best looks for halflings is (IMO) when they have well-proporioned bodies for their size, (just barely) oversized heads with distinct features (not like the bobble-headed halflings of MToF), and large feet.
Sorry, but, no, for those saying putting a hat on an elf makes them look human. You really think putting a hat on
Will make her look human? And, yes, I know that's the 3e elf iconic. I'm in a hurry and that's the first pic I found.
