Im super proud of my hideout so far. Please give me some advice on improving it.

Here it is here I love the building system. It can be a bit restrictive at times, but with a little creativity you can pull off some amazing looks. I love placing rock gardens, it's all about using the right ground textures plus the right trees. The best ones are the ones with rocks and lanterns at their base, they look so natural. Sightlines are also super impotent, best to place the small trees first and use the big trees as background. Dont place the trees to close together as they'll clip into each other. Space them out and use mossy rocks and bushes to fill in the gaps.
