Winshield frost - backyard landscape

There was frost on the car windshields this a.m. Tried taking a shot from inside the car. This is the backyard which I shot from inside the front windshield. Did not want the ice crystals to be in focus. The sun was too low to shoot for a starburst high in the trees. Ended up getting part of the van in left of picture.. I liked the silhouette effect of the tree brances--sharpened a bit.  By the time the sun high enough, the window no longer had ice crystals. The ice crystals created a filter effect.  I tried the back window too but it had the heater wires and with the slant of the windows could not get a composition I wanted.   Hope I have more opportunities to get a better shot this winter
