STR,
IMO, the "hazy" views of WTC1.v2 make it look more realistic than ever, although I can't quite say why. Perhaps it's the fact that there are precious few times that the sky is actually that shade of blue shown in your other renders, if ever (it looks like a morning winter sky more than anything). Or, perhaps, we encounter that "hazy" sky that you show in your render more frequently, and for longer periods on a cloudy day, than we encounter that shade of clear blue sky. Or maybe, it's a variation of the
uncanny valley effect, in which the sharp, crystal-clear details look less realistic and more prone to nit-picking (relatively speaking), while the vaguer details shrouded in the mist more or less still look like their real-life counterpart (I know that's not the uncanny valley effect is actually about, but bear with me).
Well, whatever the reasons are, your "hazy" renders have brought WTC1.v2 and vicinity to life like never before. And we'll just see how lifelike the renders are in a few years, during a day with a similarly cloudy sky.
