Yes, you do have some specks as seen in the shot by MakisM1 above. To get the screen he has shown you, use auto-levels in Photoshop. You might want to try something like the Rocket Blower to try blowing off the specks, but if you can't see them at f/32, then you probably can wait on doing a more thorough cleaning.
In some cases you can use the Equalize option to really bring these out too.
What seems odd to me is how there seems to be layers of exposure from the f32 shot, almost like the cleaning was too aggressive and layers of the AA filter or sensor was removed? On a properly cleaned sensor, you might get some dust bunnies, especially around the edges if you aren't careful, but I never get those graduated sections.
