Hi, thank you for writing in with your question. Guidelines for this technique are covered in Guidelines and Standards for Tactile Graphics, 2010. This can be retrieved at http://www.brailleauthority.org/tg/index.html.
If you have deemed that a 2 dimension approach is appropriate, using the method you describe (right or left view of the animal) maintains the vertical and horizontal aspects of the print graphic. You might want to visit Sections 3.6-3.6.2, 11.2.2, 6.11.
Hope this helps!
