Texturing an elephant?

At the moment, I’m trying to create an elephant in blender. I got the model and the uv layout finished. I also created a normal, ambient occlusion and cavity map. But Now I’m not quite sure, how I should texture it. Should I paint the complete Texture myself? Because At the moment I’m using photos of elephant skin and stitch them together over the Layout in Gimp. Isn’t this kind a cheating? How would you create the texture?

Cheat where you can. If you have reasonable good images use them and do a bit of manual painting to hide the seams or parts where you images are lacking a bit.

Ok thanks! I will continue like that then.
