I am sitting here remembering Final Fantasy VII-XII and how after each battle, the characters would do their victory poses while the theme song was playing. I thought it would be neat to see something very similar for dungeon runs. Instead of the Duty Complete, it should be changed to Victory!
The poses at the end are only emotes right now, but I'd love to see a Dragoon spin a lance and end up in an awesome pose, a Monk throwing some punches and kicks and ending up in a pose, etc. So in other words, give the Jobs specific End-Dungeon Victory emotes.

All while the camera is spinning around the party and the theme is playing. lol
Also, I was also thinking of making the dungeon reward EXP and items distributed to each member based on performance, or just equally. Have a menu screen pop up and display the EXP and item rewards after the party is done posing.
Just a little idea I thought would be kinda cool. lol
Updates:
Obtaining more poses for further personalization.
More job poses obtainable after certain requirements have been met. Ex. NM fights, Dungeon Clears, Achievements, and Quests.
Class Poses
Class Poses will initially use the current emote as a victory pose. If additional job poses have been obtained, those poses may be able to use on your Class.
