Bokeh is great, but the main problem is likely the blown highlight on the flower. Your eyes get drawn to that bright spot and you don't notice the rest. For the average voter who spends 5 secs looking at the picture this is all they will notice.
Hmm, I'm a bit puzzled on this one. 4.99? I'd likely have given it a 6. I think the composition is nice and the bokeh is quite nice here. Umm, well, it was a flower. That probably made the score a bit lower. The flower is just a bit blown, that doesn't help. While I think the background is properly exposed, the greens of the subject are a bit underexposed. So it looks like tough lighting. You could probably have changed things in PS a bit, but you are limited in basic editing.
