I love this one - the last one of the bokeh group I'm commenting on. Of course, I'm very partial to orange, but I also like the composition a lot. Bokeh is good. The whole image is a bit dull in tones - a touch of brightening with the famous levels - or curves - will probably make this pop off the page. My vote is with this one.
I would go with this flower, just because the white rose is always going to have blow-out issues.
In looking at past challenges, apparently a mere shallow depth of field with a blurred background was enough to score high if the image was compelling. It seems that the bokeh definition is not being taken so seriously. Therefore, I wouldn't sweat the circles. Bokeh on this is decent.
I like this one a little better. The orange on a green back ground really works for me. I think your on the right track. The Bokeh on the other one is better though.
