I'd hate it personally if Civ7 looked like this. It looks like Civ5 and Humankind had a baby with the worst features of its parents: wooden and soulless. The art itself is technically fine, but it's very unappealing to me.
This just made me realise AI may turn out to be very useful for modders with no or little artistic background, to get a bunch of leader art which follows a consistent style. Then you'd just need to fix the inconsistencies, which would still require some knowledge of painting and photoshop, but nowhere near as that required to paint a full leader.
