Low Poly Mountain Test

I wanted to try and work on my low poly design so I created a mountain out of a cube that I smoothed and then triangulated on maya. I took two renders of the mountain one with smooth shading turned on and another with smooth shading turned off, finally I combined them on photoshop using an overlay and reducing the opacity to 70% the results are shown below.

 without smooth shading turned on.

The last picture is getting closer to the sort of aesthetic I want to be able to achieve though it might further be improved by a simple texture, more lights, ambient occlusion, or a shader which I will further explore in coming weeks, I would also like to look into achieving this aesthetic in a game engine like UDK.
