The left facing casting is obviously flawed.
Previously I purchased a similar left facing piece, one with morning glory flowers, where the hair is much better detailed. 
The Wayfair pieces are also not that smooth a casting. The right facing head is well balanced- not looking like the casting was flawed like the left facing piece. The left face is flawed - the right side of the face is pinched unevenly with the eyes not matching and a nose tip flattened on one side. The flaw is not that obvious but very clear if you have the other face to compare.  A bit of car body filler, sanding, filing and painting would not only fix the obvious flaw but if you want, you actually can change the face to have a more "roman " nose like the Mucha art nouveau works that inspired these figures.
I am going to contact Wayfair and see if they can send me a less flawed left facing casting as the delivery service was excellent- It came on the day they said it would come.
