Transitions and Animations
Transitions are important to consider with any menu design. They need to be fast enough so immersion isn't broken, but they also need to not jump from one area to the next otherwise you will again break immersion. My next step will be the animations, but for now this is my plan.
Opening the pause menu should look almost like billowing clouds expanding from the center to fill the screen. To the menus from the main pause menu there would be a black billowing effect from the inside that dissipates to show the menu. The sub menus within the menus would slide in to mimic LT and RT.
To make the menus feel less static the black and green holograms will have a slight movement of the lines and flickering. The goal is to resemble the typical blue holograms from the Star Wars universe. It will be important to do this animation in a way that it doesn't take away from anything else in the screen, but make sure it isn't too subtle as well. There is a chance that this animation could be too distracting so a backup to that idea is to have the background of each screen move. That would be the cloud texture moving around and the location background to have something happening on the screens or around. Whenever a character is shown in a menu they will have an idle animation where they shift on their feet.
