Except for the sky and sun your picture's entire range of tonality lies between 10 and 100 on the histogram. With such a limited range of tonal values for the real subject (the cityscape), it is relatively drab and lifeless. That could have been changed entirely by concentrating on the cityscape and ignoring the sky, but that has problems as well.
The most significant cause for this situation is that it is shot directly into the sun. That puts everthing in the picture at a disadvantage for two reasons - 1) there is always some degree of glare or forward scatter when shooting into the sun, which reduces contrast by veiling, and 2) the main subject is essentially silhouetted.
Perhaps you are going to suggest that the primary objective here was to get the best possible PP on this image, accepting that you start with 2 strikes against you, and my answer to that is that you are to be commended for a good job of PP, but the image is still suffering from a lack of vitality.
You may also be thinking that you really like the veiled, soft shadowy look that it has, and you are quite entitled to be of that opinion. It does have a certain quality about it that is appealing.
So, I think that in the final analysis there will be a rather wide diversity of opinion about the shot, overall, rather than the unbridled enthusiasm that you were probably hoping for. Personally, I think there is something in the image for everyone, but I do think you will get mixed reviews.
