the purple-blue tiles. it seems its not really a roof, more a
floor of a 1st storey cause there seems to be a door (lower right). on
the second pic it looks like a connecting terrace
Tiles are actually cut that way though
... And honestly, I doubt he could cram much more detail in that open
of an area.
Yak, very nice architecture, I like it. I don't
think you have to go as far as making an ass load of foliage
or something like that, but messing around with the "dust
particle" effects would be a good idea, especially in the area
shown in screen #6/7.
It also seems like there should be some
more bare wires and such. But, that's just some extra
detail.
Anyway, get optimizing, I
suppose.
