Low Poly Desert Island

-I made this as a test project.
-Low Poly environments and basically all of low poly are my favourite, I like how they are simple yet beatiful.
-This one represents a little island with some mountains in the back and a tree as the main focus.
-the whole project was made in Blender, except for some minor details that I fixed using Gimp
-Sorry that I cannot provide more pictures of it (different angles) but I am going on a trip and don't have enough time to render it all
- If anyone finds any really crucial problems with the picture please leave feedback, that would really help me out.
