I played a bit with the Sapling plugin for blender (which can be activated under "UserPreferences->Addons->Add Curve"). This plugin alows you to generate really nice trees in blender by defining how many branches/leafes/which angles/etc your tree should have.

I used it to generate a tree and generated a four seasons gallery by changing the leaf textures and the colors of the scene. For the autumn picture I generated a particle system which adds a particle for every leaf and makes them fall down.

I have 4 blender files to download this time spring, summer, autumn and winter

I also uploaded the leaf-textures for the spring leaf, the summer leaf and the autumn leaf
