So this is pretty late, but I just finished cleaning it up. It's an illustration inspired by a drink called a "Green Vesper." The Vesper was "created" by Ian Fleming in one of his James Bond novels, and to my understanding it's mostly a very specific kind of martini. The green version just substitutes absinthe in for Kina Lillet. Big thanks to Kali Ciesemier for the help and encouragement with this one!
