Not bad, feels like its missing something, definitely will play around with some lime or lemon juice, maybe throw a few mint leaves in the shaker next time.
Fortunately, we all have different tastes :) This was actually not that bad. The Bourbon brings in a nice change into a "tropical" cocktail. There is a tartness from the cranberry juice at first that quickly switches to the sweetness and the Bourbon shows up at the end. Maybe it depends on what Bourbon you use? I used Knob Creek 9 year old.
