@etcmike, Literally speaking you've captured some amazing and beautiful pieces of nature and i want to say that in first glance it's reflected as an shadow image of some kind of Bird, and the effect is so awesome for sure.

And in my opinion no one can deny one thing and that is, nature itself an great Artist and Unique Architect because all these colours in the sky and cloud formations tells the whole story and many get the Inspiration through these kind of scenes.

And while watching one more aspect is highlighting and that is, in some pictures the effect is portraying as clouds are forming an Aeroplane, and it's reflecting as nature is doing mimic of man made creations.

Keep up, explore and enjoy the aspect of nature. Wishing you an great day and stay blessed. 🙂
