I do really like the trees in the background, and I think sometimes these sorts of builds with this sort of style simplicity is the key behind them. Again the structures look sturdy, and well supported, and the overall design looks pretty good well done :)

From the screenshots this looks really nice, I agree with SilentWhispers on getting a video tour, I think this sort of build a tour would make it look better because of the style, I think the colours work well together and the map is nicely terrained. Have you thought about maybe adding some animals...

The structures are nice, I like them, one thing I would say though is, the terrain looks super voxeled, if you edit it a bit too look a little more natural, this could be a really good map, and one that could definetly be added
