the bokeh helps to give the illusion that this is a regular-sized daisy, since you have no point-of-size reference to compare it to. Here the title was very important to tell me it's the tiny variety. Nice!
Definitely meets the challenge and exhibits proper bokeh. The subject matter leaves me wanting (not because it's a flower - I have nothing against flowers - it just lacks a "wow" factor for me). Nice composition! Good luck!
Very pretty. Nice use of off centering. I think I'd use Neat Image to soften the grain of the background just a bit. I might also whiten up the petals a bit, as they have a slight gray cast. Having said that, still a good choice for the challenge and it certainly uses the bokeh effect.
