@etcmike, In my opinion clouds are reflecting as Bird Clouds and giving an beautiful effect for sure.
And in my opinion these pictures are Evident for telling how artistic is nature because, in every picture we can see the differences in the colours.
And every colour is healing and in my opinion we can call the nature as Live Art because it will never stay as it was in previous moment.
And in last picture the Sun is reflecting as Red Star and spreading the strong Red effect and it's eye-catching to watch. Stay blessed. 🙂
