So, after taking feedback into consideration from the poll I did on what Alice's new battle size should be and after a lot of testing, I've ended up on this size:
I feel like this would be a pretty good size for her and it also doesn't lead to her disappearing off-screen as before.
For those who liked the previous size I showcased more, I'm sorry. Another issue that cropped up with that size is that the command window for Alice would go off-screen, so you could only see 2 of Alice's commands, so that size was way too big for the game to handle. If she were the only character, then it could potentially work as I could put her in the middle of the screen, but alas, that won't work in this case considering she has companions.
I hope to hear what you think on this matter and if you're happy or not with the final result!
EDIT: This is also her final battle size for Chapter 3 and I plan on making her grow bigger in combat until this size. She won't be this size in battle for all her sizes.
I also forgot to show you what Alice now looks like in her smaller sizes in combat; this is what she looks like now:
