"Proper" Land Rovers, as I like to call them, have square fronts and flat windscreens. The shape of a Land Rover is so instantly recognizable, at once both nearly featureless with its flat panels, and completely unique with its "tumble-home" wheel arches, sloping triangular roof, minimalist bumpers, scuttle vents under the windscreen, and other quirks of appearance.
A successful replacement for Defender will require a design that ticks all the boxes of utility, durability, functionality, and adaptability while satisfying the nostalgia of rabid fans and followers all over the world. It will, of course, need to meet ever-stricter standards for emissions and safety in a multitude of markets, and hopefully do better in terms of reliability than its predecessor. It needs to not just do all of those things, but also do them with that uniquely British sense of perfectly understated classless sophistication that seemed to be "bred in the bone" of every Land Rover, with a few notable exceptions, from the very first 80" all the way through the end of production in 2016.
