Here are a few images from previous assignments that I believe have decent bokeh. My objective with each of these images was to compose the image so that the background provided "context" for the primary subject and contributed to the overall image design without being too distracting.

Tulip and Friends
85mm macro lens, shot with an effective aperture of f3.2 (a setting of f2.8 on the lens barrel) to limit depth of field
The background is perhaps a bit too dominant in the Tulip image because of the saturated colors; however, the limited depth of field still helps to reduce the dominance of the background and focus more of the viewer's attention on the primary subject. To create this image I consciously searched for a tulip that had enough separation from the background so that the background would be softly out of focus instead of in the distracting "in-between" focus range. (This image is essentially "straight from the camera" and I could perhaps do a bit more to enhance the "pop" of the primary subject by tweaking the contrast and luminance of that flower and reducing the saturation in the flower directly behind it.)
