Yeah, the smiley face is part of it.
It was shot through a windshield, which, while driving through Missouri in the summer, had collected its fair share of unfortunate bugs. I think there had even been a few sprinkles of rain.
Possibly, because I don't speed (that way I don't have to constantly be on the lookout for cops). But I took it more as an overall seal of approval--"Well done, my good and faithful servant!" so to speak (if in fact it WAS a thumbs-up emoji from God, and not just a random pattern of clouds viewed from an angle that made them look like a thumbs-up emoji).
