This is a high poly Weeping Willow Tree. It is detailed enough for closeups, or can be used in the background of a scene.
All formats are in a .zip file with their textures and the models. There are two models: the wood and the leaves. This is so it is easier to UV map the models and apply materials to each.
Textures that come with in the .zip are the willow leaf image (alpha-masked), the willow leaf normal map, and the bark texture. The UVs are set so all you have to do is apply the image. Repeat the bark texture 3 times on the X axis, and 12 times on the Y axis.
(One or more textures on this 3D-model have been created with images from CGTextures. These images may not be redistributed by default. Look at the license on their website for more information.)
(For the thumbnails I added a level of subsurf to the leaves. You may want to do this for close-ups, but it is not necessarily needed for background shots. The model does not contain the subsurfs.)
