No man, not your fault.
Pickup is not an exact science, it's an artistic science of sorts. Just remember that these methods are not guaranteed to work, people still have their free will and issues that will make them react positively or negatively to you. All we're doing is increasing our odds.
I like to think of a lot of these types of arts like painting. Intelligent, methodical artists like Leonardo Da Vinci and M.C. Escher were scientific and methodical, and produced technically beautiful paintings; but there was still free-styled art happening with their scientific approach to painting. Other artists, who have no grounding in scientific aesthetics, they produce shit for art. Look up Leonardo Da Vinci's unfinished and failed paintings. Sometimes the method just doesn't work; the science isn't perfect.
Pickup art is similar as an art form. It's social art. We can apply scientific method, and it will only help us, not ensure success.
Those girls were just one of your failed paintings. It just didn't work that time.
Start a new painting, bro!
