Yeah, I hope the next updates are to the UI. For comparison the BG3 interface is mostly this...

The other interface panels (Equipment, Inventory, Spellbook) just repeat the information shown there again, but in overlay for each avatar displayed together.

Map panel looks like an enlarged minimap with a key to the lower left.

A bit sparse there, I thought it was more of a placeholder but it hasn't really been updated much aside from the addition of some new icons to the main hotbar and such.

I enjoy seeing more of those little embellishments like in the OP, an ornate vibe with some ephemeral and hand drawn call backs. I'd love to see a more modular design and aesthetic for the UI too. Just seems like the sort of thing we should be able to reskin and play around with a bit at this point. I can picture many different themes they might deploy to give it more character, and make a playthrough feel a bit different even down to the level of UI flair. Right now it takes up the whole screen, but doesn't make a whole lot of use of all that real estate.
