The full request by Lionel was actually more developed than what I wrote in the subtile. Twitter is obviously not suited for him.
Here's the long story: 3 people dressed in steampunk fashions picnic on the grass at the foot of a blooming cherry tree for ohanami. However on a closer look the tree is made of brass and each flower (on tree and falling) is a tiny drone using the tree to recharge its energy. Foreground is a country setting while in the background we can guess a steampunk city with flying zeppelins. Ah, and of course one of the 3 people needs to be a neko-girl and they have a small pet (real species or chimera) running around the napkin or standing in their arms.
