Arigato! Also, just so you understand the title:
"Mono-No-Aware (物の哀れ) - It essentially captures the concept that beauty is subjective and that our senses to the world around us make it beautiful — especially when that beauty is impermanent, as it makes us appreciate it more. The best example of Mono No Aware is cherry blossom petals falling during the springtime."
In short, Mono No Aware teaches us to appreciate what life gives us, no matter how big or small those things life gives us may be, as they won't last forever, thus meaning we should cherish these things life gives us instead of pushing them aside, like most people do <3
So, basically, the art is showing Mono No Aware via the best example; Cherry blossom petals falling during the springtime <3
