I propose to make the loading screens responsive, which would show different official art depending on the decisions made in the game and the progress in the quests.
Also It seems very strange to me that the loading screen shows Will when he is dead and no longer involved in the plot. It would be very nice if the artists of Larian Studio draw the loading screen with Minthara, as for the rest of the characters. If someone is dead, it's a bad idea to show them on the screen.
Larian can also draw Zevlor, Khalsin, Kagha, and so on, depending on who the player supported in the quests. This will make the loading screen more enjoyable.
It might also make sense to implement this in the form of an in-game gallery, where in order to unlock fan art you need to make some progress in the game.
