How can I add a reptilian skinned texture to my model? I have no clue how to texture, so any help is greatly appreciated.
To texture, you can use Blender internal texture, or UV unwrap your model and paint the texture right on the model.
If you can live with its looks, Blender internal texture is can be applied very quickly. Here is my test:

I used Voronoi here. Its base texture looks somewhat reptilian. By playing around with the variables you can get it to look like reptilian skin. Note that I mapped it in Normal channel to make the skin bumpy.
Thanks! That helped out a bunch!
