Something I find truely fascinating is, as we all have unique eye shapes, even if we use the same lash map our results may differ. You can see here how the 12mm appears slightly shorter that the 10mm. If I were to change the lengths to using 14mm x4 and completely skip using 12mm, I could achieve a more uniform long to short lash style. I actually dig the long, short, long lash style though and this particular look is one of my favourites! What are your thoughts?
