I've learned how to change the avatars by editing the game files (but the game still need an easy way to do that). Here are few more suggestions.
1. Bigger avatars:
The avatars are too small and the 4 characters don't fill the height of the screen, they could be taller, a rectangle instead of a square (like Baldur's Gate).
2. Option to hide the "+" icons:
This game requires to keep points to advance in further levels, so we will be most of the time seeing those "+" icons over our portraits. It would be nice an option to disable those "alerts", we already know that we have unspent points, don't need to be constantly reminded.
3. Effects in the portraits:
All buffs stacks horizontal from the portraits, disturbing the vision, for example I don't get Leadership to not see all the time the portraits with the leadership icon aside. The effects could be stacked under or in the portraits or in them with taller portraits.
