TS, please take a few steps back to cool down your negative perception of the comments posted (and a few of these posters are pro and serious hobbyists).
Firstly your title is already a very attention-getting one. In the minds of most shooters, "Noctilux" is like the AMG or M5 engines. People expect high performance, or beauty from this lens. When you post an image screaming Noctilux portrait, it is not unreasonable to expect a high quality image. But if you start leaving behind reflector, messy hair, poor colour control, etc you must expect a lot of comments not to your liking.
You are making yourself sound rather silly when you start making all kind of arguments and contradicting comments to defense your views.
If a Noctilux is not the right lens for a portrait shot, then why post one and scream "N... P...."?
If the purpose of using a Noctilux is to shoot at F1, for low light work, why a portrait with reflector, bright natural light (as seen from your reflection), etc...
If you post this image as a unique image, the people here couldn't see any uniqueness in your image, and as such they are asking you to tell them.
What I can say is that you are very lucky that these people bother to make any comments.
I am sure if you have posted an image like this, you would not have gotten all these unwanted comments.

btw, who gave you the impression that a "Noctilux" is not a portrait lens?
