Hey there!

Terrain:
I think you're terrain has really great qualities to it. You have a nice variation of blocks as well as use of some water/wheat areas. My suggestion however, so your plot doesn't look so cartoon like, is to mix grass in with the terrain too. I think keeping some grass in the the terrain is necessary. I love the cliff palette though!

Organics:
Really lovely and original organics. Well designed and made, good job, I don't think the tree needs that long vine hanging from it however.

Structure:
You have a nice structure on your plot, and various other little ones. They all fit in together. I think personally you will need another structure like the windmill on your plot over in one of the areas that are empty, like the place I put this review, for example!

Good luck! Dutty :3
