To generate a low polygon model we used Andrew Sinks Low Poly Generator that you can find on lowpoly3d.xyz.

Here you can easily decimate the model to get a cool looking low-res statue! 

Next will export our model and then re import into Blender to fix any overlapping faces or overhangs.

Fixing geometry

Inside Blender, we can delete extra faces and fill in any holes generated during the low poly process. Then, use the fill face command to rebuild the geometry.

Fixing overhangs

To fix any extreme overhangs, we can pull faces by going into the sculpt mode. We used the Elastic Deform tool to help pull faces so they are at a 45 degrees angle. This will help cut down on the amount of support material.
