I love the left half with the frosty flower, but don't really like the distracting flowers on the right hand side. I'd suggest toning those down. Even better maybe, crop tighter on the main subject and clone out the pink blossom(s).
though interesting, the strong coloring of the bg flowers takes away from the gritiness i would associate with a grain challenge. they also steal some of the show from your main object. i'm thinking black and white would help make this a stronger entry for this challenge
