Not that many people are aware of it, but Bronica's lenses were noted as some of the BEST medium format lenses in terms of bokeh; many older MF systems used those German-made lenses with awful heptagonal diaphragms and had bitingly-sharp optics with all the spherical aberration corrected out, leading to harsh, yucky bokeh... Bronica's Japanese-based ideas behind lens design and lens drawing issues were very different.
The old Zenzanon 150mm, the pre Pro Series model, was a known awesome bokeh lens.
I like your first skateboarding photo--nice point of view. The dog shot isn't so good, and the wooded scene is actually pretty decent. Good monochrome conversions too!
Disclosure statement: I am a Bronica owner as well! SQ-A baby, all the way, And SQ-AM.
