I will definitely put an eye on this project more often from now on and if your game continues to develop in right direction i will definitely put more energy and resources for further development.
If you need any advice about general economics i would suggest you to get in contact with
CryptoDatabase. He has just released (although still in beta state) his second MMORPG game and has many years of experience in game development.
Or maybe get in contact with
rghmodz and his snake game created with Unity assets. Anyway looking forward to seeing further progress.
yes I did get to talk to cryptoDatabase and am in contact with him. Very Helpful!
Meanwhile also updated the video and main screenshot..
Still very initial but things would start taking shape soon.
Now everyone's city would look as per their creativity .

I am glad it helped, i know he is very busy with releasing final version of his game Valerian Universe, as you have probably figured out for now. Have you maybe talked about any kind of collaboration in the future or even maybe partly sponsoring your game?
Anyway you game's screenshot looks really great. I see lots of improvement. Keep it up. Will stay around. I know this takes time and not everyday you feel motivated for what you do, but never quit.
