After looking through them all and reading through the comments already said, I have to say I’m definitely a big fan of the 4.1 version of the textbook and character sprite. In my opinion the others have the the character portrait too small and it seems like with the 4.1 version of it you’ll be able to do more with the sprites like more dynamic poses to accentuate what they’re saying and add to their personality, unlike with the smaller ones or the others that just show their face. Also Id just prefer to see the whole body sprites because your pixel art is amazing!
With the overwhelming response for 4.1, I believe that's what we'll be going with! Though, Foxekai is looking into potentially making a modular UI that can be adjusted in game to the player's liking, so that could fun, too! For now, though, 4.1 checks all the boxes! Thank you!! Pixel art is challenging, but when done right, it's so cute! Now I just need to make the 112+ characters in the game and all their expressions...
