Fill a cocktail shaker with ice and add the vodka, orange and lemon juice. Shake together until the outside of the shaker feels cold.

Add a few ice cubes to a tall collins glass, then carefully double-strain the cocktail into it. Add more ice to fill the glass, if needed, then slowly pour the Galliano over the top. Thread the cherry and orange slice onto a cocktail stick, then place across the rim of the glass.
