hmm maybe adam =), but birds wouldn't really fit in the little story i have in my head for this, since the air is supposed to be toxic..
little update! Added some extra stuff in there that can hardly be seen :p, worked on background buildings and remodeled the middle building. It still needs a lot more detail but at least i got a base to work from now =). I managed to get the entire building on a 1024x2048 sheet, with the parts the player can get close to still at high pixel density.
i started thinking about my second perspective as well, i will probably go with something like this, which shows some stuff more up close and gives a nice view to the other side. I need to fill this up of course, but with the collection of props i have now it shouldn't be too hard!
