well ... it really does look enhanced, ive had a few doubts since i wasnt fond of some of the model showcase like sakura cus it looked like she aged 50 something years old but yeah now you can see why she got that witch nickname. Atleast they didnt look outlandishly far from their original look, and the male characters definitely look more battle hardened/serious. The background of the scenes also upgraded and even looks quite extravagant.
Although I am still bothered by Shin's unnaturally very pronounced collar bone.
All in all, it's definitely not a very huge upgrade since the outdated-to-be chapters still looks nice but it should be a good QOL improvement for Kuro since he posted somewhere here that making the renders on blender actually takes him less time and is more efficient. Hopefully this really means that updates will get pumped out faster/ or at least more content per update.
