I recommend using an interesting Rum here to make it less cut and dry and more interesting. I bit too dry for my taste but that can be adapted with a funky rum and maybe including 1/4 of simple syrup.
I feel like you need a good smoky Mezcal to have a chance against the Chartreuse, otherwise it disappears in the background and it feels unbalanced, albeit still good. Montelobos Mezcal works for me.
