thank you all for your replies, sorry if not responded quick but these times got lot of things to do.
Now i really have lot of things to work on.
just learned how to add decently a bit of dirt over those surfaces so @defmaka i’ll certainly do that, and i’ll try the grass in the cobblestone.
@Jamie B you caught me, i added the birds very quickly short before opening the post, now that you made me notice that only a storm of Pteranodon might be so big :P.
For the little gaps in the front they are actually sliding doorways, and those are the true dimensions of the building(they used it to build ships,long long time ago).
The problem here is to make visually immediate that this is actually a \Huge door and the other normal ones, as i would like to avoid people in that, I am really not good at character modelling.
Surely as Xerubian pointed out The DOF create more mess about proportion, the problem is that the buildings out of field are poorly modeled as they are industrial horrible building with(where they actually build ships in).
Thank you all for your feedback, it’ll take me some time to apply those modifications, as soon as i’ll do them i’ll post here.
