Maybe its the subject matter? You do realize that 90%+ of the emotion and mood you feel from a photograph comes from what your looking at. Look at your example of Paris vs the Hospital Bed.
Hospital Bed: Mother and her baby. Soft lighting. Pose expresses movement and candidness. Composition is great. Brings out nostalgic feelings because of the new life and the warm quality of the lighting. Its EXTREMELY narrative; even the DoF makes it seem timeless and as if a real "moment" was captured.
Your picture in Paris: Is (composition-wise) unbalanced, you have a big solid dark heavy building and you are attempting to balance it with sky. and not any where NEAR enough to balance that. Its dark, it is gloomy (underexposed) and it is completely still. No narration at all.
So what would you expect? You could have taken the hospital bed photo with a digital camera... you could have taken it with a cell phone, or a pinhole camera and it wouldn't have made a difference. Because its the mood expressed by the timing and the subject NOT the medium.
As an artist (I paint) I can say that what you are really trying to do is make watercolor look like oil paint. Can you have warm and embracing pictures painted with watercolor? Yes. Can you have warm and embracing pictures painted with oil paints? Yes. Will they look the same? No. Because they aren't the same.
The point is the emotion. And THAT is the difference you are seeing. The photographers above all captured DIFFERENT moods in the different pictures. And as a result the medium is IRRELEVANT.

Hope this helps; its the easiest way I can think of to understand it!
