I like the composition in the first, but I find the bokeh and the other mushrooms a bit distracting in the background. I'd be tempted to see if a bit of addition blur added in post reduces that.
The second I really like but I kind of feel sad for the foreground flower as it looks like its dying / frowning sort of.

I like the first one best. I don't find the background too distracting, but I agree with Alpha_7. A judicious blurring may improve it further.
