Will it be possible to bring own portraits to the game? I think it shouldn't be too difficult to add the possiblity and it would be a nice addition to the already great set of functionalities.
it will not solve problems in the confusion of characters, and to connect to your game is not understood which of the characters belongs to a flag or a spoon on the avatar.
In my opinion the only correct solution - to a screenshot of the character when it is created.
