Hey guys, finally I have time to post my final..
So after I have read all your kind reply, then tried to consider some of your opinion, done a lot of trial and error I guess this is my final result.
Finally I want to say thank you and appreciate to you all who have visited my thread, in particular @jonatan-moonchild , @volenck, @flamer, who gave me useful inputs. I wish to see you again in next occasions or maybe in the next challenge.
So this is my FINAL. Below I also rewrite my concept story, so you don't need to go up.
In the future, after a big war has been finished, there are survivors who save from big wars decide to build a new hope. Using the old ruined city as a base, they decide to build their home.
All in all, this is a new, an unfinished city, above the old ruins, where people who still have memories about how great their old days and deciding to build a new homeland (A- Jabu)
PS: Ajabu, personally I took this word from a local traditional language in Indonesia, Batak language. It is originally composed by 2 words A and Jabu ("A" means one, and "Jabu" means house). However, here I changed the meaning of house to a new hope/ home.
