Great macro job. Agree with Dave about the underexposure. I hope I remember this if ever I find something like this to take a picture of in "frost" or some day "snow". As the white looks like snow flakes to me.
Nicely done, Glen. I like the format, composition, depth of field, background, and colors. The undersurface of the berries is underexposed, something I probably would not have noticed at the time of the shot. A reflector or fill flash might have brought that out.
