to upgrade or not to upgrade {victoria portrait photographer}

For all of you who are interested in photography and all the techi stuff, today I tested the 50mm/1.2 lens.  A beautiful lens, but...  is it really worth the money I wonder.  I do have the 50mm/1.4.  Sounds pretty close to 1.2, doesn't it?  However, the price of the 1.2 is about 3x as much as the 1.4 which I own.  So I am wondering if I should upgrade or not.  Took some test shots this grey rainy afternoon and yes, it is sharper, has more contrast and so on.  I guess I need to do some more testing before I decide.  For now, here are some shots from this afternoon.  Some with the new lens, some with my old.  

 These images were taken with the 50/1.2
