Forgive me for being controversial.
You mention some excellent lenses here. i own the FA 31mm and the DFA 85mm. Also the FA* 24mm and the M 20mm. The 31mm and the 85mm both have a unique rendering that will add a something extra to your pictures if you choose the aperture and focus point correctly,
together with the composition.
But what will really bring a "wow" to your images is not the lens, but is you. You say you like the DA15mm, so use it in crop mode (or crop after) and concentrate on your lighting and composition. If you get those right you could use a shoe box with a milk bottle as a lens and get a good result.
