2. Companions:
2.1 I get that you are going for a quality over quantity aproach here, but I always found that one of the things that granted a lot of replayability to the series was the large roster of companions to choose from. I do still kinda miss this aspect tho.
2.2 The writing for all of them seems pretty good and promising so far and I am looking forward to learning more about them.
2.3 I wish they would voice their opinions more during conversations with other NPCs. Overall they feel a bit too passive at times.
2.4 They also seem all to be rather same-y visually and culturally, not counting Lae'zel and maybe Astarion. One of the big selling points of the companions in the series so far has always been how diverse and from all over the place the companions were. (Again, not countin Lae) they all seem to be from the Sword Coast, which I find a little boring. Everyone is either human, elven or half-elven.
They have mentioned that there are more companions to come, but Larian started with the "evil/neutral" companions first, so I'm sure you'll get your wish!

4.1 I'd love to get more options for faces or a proper face editor.
Unfortunately, not sure about this one since Larian has tried to set expectations that they will not use sliders, etc. I'm sure the rest of your character creation points will be addressed as EA goes on or for the final release.
