An 8 meter tall tree with a Flat top and Needles.

Oops. You have constructed a tree that is not quite ideal but it may survive in an Alaskan forest. The height that you chose it the best, and the needles are the right kind of leaves for a tree in Alaska because they are so narrow that they will not give off a lot of moisture. However, the branch design might make it hard for the tree to survive, the best design would have been a cone shape.

Now you can try again or look if you want to look at something that you can do with real trees outside, click here.
