Hello!
Your plot is looking great, but I have a few suggestions for you.
1.) Space Usage- There is so much great land, on the side of the hill that you are not using. Add some smaller and larger structures there, because you never want to have too much empty space. Little homes, more trees, or any structure like that really help.
2.) Terrain- I see you have terrain, but if possible, I suggest more rugged terrain, that is harder to climb up. Or smaller hills around the sides, just for that detail you need to get ranked.
3.) Organics- The one large tree you have is really good, but the smaller trees are all very similar, try a variety of shapes for your trees.
4.) Structure- Your plot has very little structure, and the structure is does have is small. Structure are things like homes and buildings, etc. Make a larger one and some smaller ones to fill space and add extra details!

Good Luck and Happy Building,
