I chose the eye placement based on the template I bought, but you can make a line down the middle and just mark points that are the same distance apart to ensure some symmetry. Using some pintape I placed some marks where the ‘eyelid’ parts would face diagonally, used the end of an exacto to punch in some holes down the middle, and lightly sketched on the clay where the ‘pipes’ would be placed along the eyes and top.
