Banjoman, I've played with the cartoon filter as well. It's an art to find the right amount of black to be used in the process, otherwise it starts to look like an engraving. It's funny the program can't find the horizon, that seems to be missing in the second shot. Maybe in WOTR they'll figure out how to increase the distance and reduce that fog.

The connecting rod out of my brain, my brain,
From out of my arse take the camshaft,
And assemble the engine again."
