I'm a Ladyby

I don't have a really good idea what bokeh is (or rather I can't describe it very well), but I do think that this image is more about a narrow depth of field than about the bokeh effect.
The background in good bokeh (I think) reinforces the subject. Look at the top scoring images. The backgrounds are beautiful. Soft. The background is what boasts, emphasises, and launches your subject at whoever's looking at it. Bokeh isn't just about things or sections of the image being out of focus. It's about the out of focus-ness supporting the rest of your picture to focus your eye on a focal point or subject.
Your background is nice and soft too, but I think that as you can see the plane of focus it pulls your attention away from the subject which is the opposite of what bokeh should do. Do you see what I mean?
You didn't get a bad score. But I think it would have scored better in a narrow depth of field competition.
Also, if possible I think you should try to export images to as wide as possible (800px). Larger images tend to do better... or rather smaller images might find it harder to score higher.
