Hi Kurt -- It'll be fun and educational to give that rare Amotal lens a good workout! Different lenses give different appearances to out-of-focus items, often in a different way when they're closer than the plane of focus versus beyond the plane of focus. Here's a good discussion of bokeh (which is a Japanese term referring to the appearance of OOF areas): http://www.luminous-landscape.com/essays/bokeh.shtml
The distant OOF bright points in your pic are brighter around the rim of the imaged circle, which usually results in a harsher look to the bokeh. I know this is a very simplistic observation, but this looks like Zeiss Sonnars, Nikkors and other similar designs like the Jupiter-8. Quite different from Leica lenses.
It's very likely that your lens would give smoother bokeh for OOF items closer than the plane of focus, where the centers of the imaged circles are likely to be brighter than the rims. I believe it's a matter of over/undercorrected spherical abberation.
Something else noticeable, particularly in the second and third photos, is a "greyness" in the dark tones; a lack of black. This can be fixed in your photo editing software's Levels control.
In the below control window, I've moved the darkest tones (by sliding the left black triangle to the right) from the 0 Input Level to 67 on the histogram. See the before and after samples in the small displays, showing what it did to the pic. This effectively dropped the darkest greys to complete black, expanding the tonal range and increasing contrast. Nice looking young couple!
