No, I did not need to say it all actually. 
I think there should be a little difference in elevation so that everything is not on the same level!
Yes, I agree with you. Thanks for the reply. : )
It’s kind of hard to know if someone made something or not lol-
eh- I would not say that entirely, but you kind of have a point there. next time for future reference i will imply what I did and what I did not.
So should I make a “showcase” with 100% free models and claim it as my own?
This is not a showcase buddy. And quote where I said this was mines. I would love to know.
Basically, saying “any ideas on what to add for my low poly build?” isn’t really needed if you’re only using free models. And people can notice what’s built by a user or not depending on how well the builds match it’s environment.
Actually the only things that are free models here are the mountains trees, rocks and buses. After that everything else was built by me from hand
Try adding some low-poly flowers/foliage and maybe some street lamps would fill up the space. Otherwise, lobby/map looks pretty good.
Unless the game is very popular, try reducing to maybe just two busses. Three looks a little spammy.
