Trees are a majestic thing, they have a very thick trunk. I look at the tree, it looks very big compared to me.
It is created by nature with the leaves on top.
In Summer, the leaves turn bright green. With the light shining on the tree. 
Then Autumm.
The leaves start to fall on the green, grassy ground.
Then Winter.
They are still on the ground. The tree has no leaves, on the tree all you can see is the twigs. 
Finally Spring.
The flowers bloom, the grass grows and covers a bit of the trunk.
Summer comes again.
The leaves turn bright green, with the light shining on the trunk of the tree.
