Alien World Low-poly 3D model

This is how I imagine an alien world looking like: beings living together in communities, close to each other, working together, helping each other, and spending lots of time together practicing all kinds of activities outdoors. In the center of this small community I tried to create some kind of monument with sacred meaning, which would depict the aliens' belief and on the extremities I placed their homes and other buildings facing the center of the community. Of course, you can move the objects and arrange them in any way you like!
