When I saw these statues added to either side of the Chronos I was surprised. Aesthetically, they are different than the dynamic, classical, style of the Helios and Luna statues. These are more in a 1930s Art Deco or Streamline Moderne style, which, while different, does go well with the Chronos itself.
But what was more surprising to me was how their hands were raised, palms up, almost in a religious pose. This vibe is furthered by the fabric stoles, kind of like a priest or pastor would wear.
They also evoke the sculptures and statues integrated with architecture typical of the1930s, which was sometimes propagandist in purpose.
So, I wonder if these statues will be off-putting to some people, right at the entry. They may feel a bit cult-ish, a little "too meaningful." It may have been good to tone this down a bit by not having the palms seemingly turned up "to heaven" and rather have them on their hips or holding a sphere or something more secular/scientific.
