An old mans' face

This face is part of a sculpting i did as concept art for a game project.
My very first model for printing purpose, i hope it works :-)
I used Sculptris for sculpting and Blender to clean up, prepare and export the mesh.
Have fun and tell me if you've printed it! :-)
NOTE: 3D Model has no color in it. Its just a rendering to show you the shape.
NOTE 2: Fixed the scaling problem. Now its about 13.1 / 7.2 / 4.8 cm
