This is also a great idea. Sometimes numbers just look like numbers- I know that as I'm grinding lately in Breath of Fire 2, I tend not to register sometimes that, yes, I should heal Katt at 60 HP, because that's less than half of her health. I just see 60 and go eh, she'll be fine, and then get torched. Hurt faces are a quick visual reference that I feel will be quite handy for players. Another good idea.
Glad you stuck around, E. Seems you're hitting your stride.
