Finding level

Like many of you I like experimenting with silhouettes and these cow elk are from yesterday morning. In my usual haunts, however, most of the land is nowhere near level, but that is compounded by the fact that many of the slopes are long and flat, creating odd references. This is shot off hand, and I never had a good reference when taking the image. When I first reviewed it, I knew the slope was strong, and often I study vegetation to find evidence of upright growing. This tree, however decided to really curl! Another clue can be found in the actual balance posture of animals, and in this case the rear leg of the uphill cow might be pretty much true, but both cows are in slightly shifted balance positions. However, I solved the puzzle of actual level by noticing the distant cloud banks with bottom borders lying flat...and level! I had to rotate about 2 1/2 degrees to compensate, and was satisfied that it now felt right to my eye.

This is cropped to reduce some of the mass of the left side tree, and it is still pretty dominant, so I am curious as to what you think.
