Since when do people tear off the fourth leaf of the clover...? I thought you were supposed to pick the whole four leaf clover, otherwise the leaf by itself doesn't appear to be different from any other...
I think the image focuses more on cruelty rather than luck itself. Rabbit's foot, four leaf clover. Parts of themselves were taken away that made them lucky... Try not to think about it too hard and it actually kind of works out.
I get that it's about the cruelty that having lucky items can involve, it just doesn't make much sense in the case of the four leaf clover. No one would just pick the leaf off and leave the rest of the clover there.
out of curiosity, exactly what kind of technique and program do you use to do this? I do most of my artwork with either illustrator or photoshop. Do you send the files as a vector file, or some kind of transparent based file? I've always wanted to know.
