SketchUp Model with Textures

From the 6 sets of 6 light to dark textures I chose one set from which to chose 3 textures (one light, one medium, and one dark) to add to my SketchUp Model. The set of textures I chose was the one in the photo below. I used the 2nd texture of each row to represent the different shades (the darker of the two).

  

I added the 3 textures to my model in the way I felt the shadows would actually lie (from the angle of the first photo). The pictures below show the model from afar showing all the textures, the model from above where two sides look like the same colour due to the different lighting from that angle, and a close up of the model.
