I am not one to nit pick, but I think the description to the challenge was changed to image grain, not the eatible kind... but, I like your picture, and I don't score low if it doesn't meet the challenge to a tee. I like it!
Where is the image grain? Your subjects are crisp and clear. No grain. The background is out of focus as it should be. If there was image grain it would be on the whole image and I just don't see it.
