Agree with Andy, I like the stump one. The tilted horizon is often a "no-no" but it seems to work here, maybe because the cut of the stump is the horizon now. I think leave it tilted?!
Cheers. Believe it or not the camera is as level as I could get it. I also check out the calibration of the cameras onboard level, and all my work levels read true. It does look a bit off , but it's the lay of the land.
