At f/32, I'm sure diffraction was a factor - maybe the most significant one - in blurring the tiny ice crystals. Also, with a six second exposure, there's a good chance SOMETHING moved, even with a good tripod. So my guess is a combination of diffraction and either tiny camera or subject movement.
Something did move ... it would be interesting to see how much diffraction entered in if it hadn't moved .. but why? I was out there shooting the same thing for three days in -10F weather and kept coming up with the same thing. I just couldn't figure it out because I had shot some ice the week before and the crystals were tack sharp. I just didn't like the compostion as well as I did with this one.
