I want to say one thing that no matter what the greatest art will be the nature because nature have so many unique creations which can really surprise us and same way can heal us with the beauty of the creations. And many people get the needed inspiration from the nature for sure.
I have small garden and growing some random flowers and i really like to admire their beauty because for me flowers always reflects as nature's smile and in my opinion flowers can give breathtaking essence to anyone and if we want to get the true healing then in my opinion we should explore the beauty of flowers deeply.
People who lives close to the nature they know the real value and real beauty of nature. And we all know that whenever we explore the beauty of nature then that gives nature's greatest essence and that's why people try to explore the natural places when they get the opportunity because they get true peace.
Whatever pictures you've shared that are literally reflecting as gems which are created by the creator of nature and one thing we can clearly see here and that is the greatest relationship between nature and its creatures.
Wishing you an great day and stay blessed. 🙂
