Well..... to my way of thinking, that is a hell of a lot better than the great majority of campervans
Outside the front roof looks a bit weird, but when you see the front bed, it is very clear why it looks like it does and that front bed is very clever.
I saw last year a flurry of Ducatos with pop-up roofs to provide the additional sleeping option, and I guess doing that would keep you under some height limits, but the permanent high roof does have its own advantages.
If you want to do any kind of distance with more than 2 people, those rear seats look like proper car seats. Rear travel seating is not some thing I have really ever looked at in detail, not having any need to do so, but when I see rear seats in a motorhome, they are very rarely appealing and seem to be more for very limited journeys and there just to tick the "travel seats" box. The Scopema RIB seats are maybe about the closest to proper travel seats you tend to see with some VW Camper conversions typically, but the ones on this van look nicer (I guess they don't have to fulfill a dual seat/bed role).
As you say, it IS a small lounge for 4 to spend much time in (especially 4 adults) but if you need a compact vehicle that can still cater for 4, this would be pretty nice (and there is the fixed bed at the rear to escape to as well).
