Bee nests should use wax blocks, not skeps as their texture. It is a common misconception that bee 'nests', or wild bee hives as it were, are shaped like a spiral or Michelin man. These in fact are representative of skeps, a traditional form of manufactured bee hive before wooden framed hives were popularised.
Natural beehives are generally found in crevices like holes in trees. Naturally, this is not practical in Minecraft. However, beehives are sometimes found hanging from branches, a la the implemented design. These hives are, of course, made from beeswax. The beeswax texture proposed would be perfect for bee 'nests'.
I would even suggest that the manufactured hives be replaced with skeps (and renamed a Skep), using the present texture for a bee nest, albeit with only one hole. Skeps would be made from either sugar cane or wheat, make in a dome-like fashion on a crafting table. Skeps would have to be placed on a block and cannot be suspended. Everything else would remain the same. Otherwise, the present wooden beehive could remain and the skep texture removed.
I feel Mojang has a responsibility to promote accurate knowledge, and given the proliferation of misconception regarding the appearance of beehives, they have a duty to be accurate.
My first thought upon seeing the hives on youtube were that the bees and the hives are both a bit large... the hives make enough sense compared to the player, but they dont look quite right hanging from the natural trees that are shorty short compared to steve. as for the bees maybe the drawn bee can get much smaller but keep the same hitbox, so it seems more like an insect and less like a bird but still maintain the ability to hit it.
as for the shape of the hive, i dont see a reason why we cant go a little inaccurate with it and make it look like a paper wasp nest when it spawns naturally, but i do like the idea of keeping the existing model as a "manmade" variant, i feel like a slight redesign needs to happen just to keep it from looking like the trees are struggling to stay upright with the giant nest hanging off of them.
another idea to fix the tree/hive scale issue: make hives only spawn naturally under exposed wood branches on supertrees
