Agree, technical aspects can become mountains from molehills, when the image as a whole is what counts. Look at some the famous images from the likes of Cartier Bresson etc, and they have been picked to pieces technically over the years, yet they remain iconic images of 'the moment' However, here is the bottom line.... unlike when Bresson, or even Bailey, etc, were first getting their names out there, today we have the internet and everyones a critic... YOUR mission, should you chose to accept it, is to sort the wheat and take it on board, whilst politely blowing the chaff into next week.
As a thought for you personally, taking on board what you just said about not getting the photos you want.... start again. Go back to basics and take an image at a time. Decide what you are trying to achieve with the shot [or small range of shots], use the knowledge you already have to try and achieve that aim, or at least get on the road to it. Then post it here, laying out exactly what you wanted, what you got, and asking for guidance on getting from your current point A to your desired point B [this might be the actual shooting, or the PP or a combination of both] rather than general critique. Then reshoot armed with that advice.... and keep reshooting and asking until you are happy you got what you wanted before moving onto the next idea or desire.
Oh and when you get it to where you want - print it! Get it done nicely, maybe on some art paper with a big border, and keep it safe. Over time you will build a printed portfolio that will remind you of what you have achieved when you get into the mood you are in now.
Go on.... give it a go...set yourself a challenge to achieve a style or image you have wanted to do and feel you have failed at....
