Those designs seem... fine? The imagery seems quite traditional, the largest deviation seems to be the choice of strong unifying colors across whole windows, while having colors that aren't traditional to the rest of Notre-Dame, such as pinks and yellows. The windows they're replacing seem pretty boring and uninteresting, I can see why they're taking advantage of these renovations to also spruce up these windows with new designs (itself a many centuries long tradition). For reference, here's the windows that are being replaced: https://commons.m.wikimedia.org/wiki/File:Notre_Dame_Cathedral-_Window_of_Chapelle_Saint-Clotilde_by_Eugene_Viollet-le-Duc.jpg https://commons.m.wikimedia.org/wiki/File:Notre_Dame_Cathedr...
