Interesting photo. I've been looking at it for a moment and trying to decide if Neat Image was used - and can't decide. Bumping up one point after second look.
This is an interesting shot for a grain challenge. I just finished commenting on another shot in the challenge that I felt suffered from a loss of detail due to the noise, and the subject was similar to yours in that it was plantlife that had fine lines. In your photo, which honestly has finer lines, the detail does not seem harmed, and the softness added by the noise actually helps the shot along. If this shot had been very sharp, I think some of the effect would have been lost. Good job.
This is a nice photo. However, It leaves me wondering whether or not the grain really enhanced the image. To me, grain works best in photos that are dark, contrasty or moody, or to provide an "aged" look. This seems to me like a good image that had grain added to it for a contest, rather than an image that was enhanced by the use of grain. Keep shooting! :)
8 - Good use of grain for the Challenge. Criticism; not much, maybe 'wider', but I like it like this. Colors are nice and 'soft', you retained the 'feel' of the seed heads, even with the grain, so well done. The 'bokeh'(?) is nice as well.
