FYI, sensor dust does not show up at large apertures. One would need
to stop-down to f/16 to start seeing anything. These are all far above
that.

I've found that extension tubes do amplify the effects of sensor
dust at apertures where it normally wouldn't be a problem. #1 of
your shots does appear to show some spots that look like sensor
dust.

I understand it has something to do with the fact that as the
extension tubes push the lens further away from the sensor, and
this is what gives the higher magnification or more correctly
allows you to focus closer, the light path from subject to sensor
is more direct/linear. Since the light is not as diffuse, it
highlights the sensor dust more.

Hope I explained it well enough.

Sorry, meant to comment on the actual photos too.

I think the exposure is just a touch under what it should be.
White flowers are difficult to meter and often they end up a
little grey as yours are. Might need to overexpose them by 0.5
to .667 stops to make them white again.

The depth of field is ok for most, but one of them (sorry, can't
remember what # it was) has the DoF very thin through the stamen
and just looks a little odd.

Other than those minor comments, well done :)
