With more than half of them I can tell that you're experienced with thinking about composition. Painting makes sense. In some cases, the painting is in a category I'd call "Painterly," which is what I use in my own head to classify a certain type of shot I see a lot here in which the image looks very much like a painting - strong colors and lines, very still / static image with no implied movement, no fleeting glimpses of a smile, that sort of thing. In those kinds of shots, (and for my money ONLY in those kinds of shots, but everyone's taste varies) then a heavy hand in post processing makes sense - heavier than you went here, like with the garage shot at night. I don't personally like super-heavy PP on more people-oriented dynamic shots where something's happening. But I like it (or at least appreciate it) on those painterly compositions. So if you're going for that, then for my 2 cents you can crank it up a notch or two on those shots.
And finally as has been said, some are pretty flat shots with not much to tug at the viewer, and probably don't belong in any kind of showcase of your work. They have something to them that interests you, but in a portfolio they say "I don't fully understand what others respond strongly to." No shame in that, by the way, it's a tough thing to get right.
