Can this manga's art be classified as Shoujo Art?

Is there any Yuri series whose art is as sparkling as Shoujo manga?

i just started reading The Feelings We All Must Endure and that looks like straight up Shoujo, with its panel and dialogue layout. — Until you start actually reading. The protagonists are all university+ age, and discussed topics also don't quite seem to be the standard shoujo demographic stuff

all that to say: what is and isn't shoujo probably has drastically changed in the past 20 years.
