I found this nice 3D scan of a Groot sculpture by Åke Mora Temnerud (http://www.123dapp.com/catch/Groot-High-Poly/4608564). The sculpture was made by Clamhan Studio. Follow them on Facebook : facebook/clamhan studio. Original mesh for a project of Visit Cards with Augmented Reality developed by Twin Force (www.twinforce.es).
I added a color mesh and an STL file. I sculpted the mesh, filled holes and scaled and oriented it.
