I've noticed almost all the fire horse images this year are limiting or eliminating excess fire overtones, which makes sense given the times (that said I love the fiery vitality of Kakapo's horse). But I've seen some interesting brush art that could be a alternative (note: someone should check the characters if we go this route as I just pulled this off the net):
Has that vitality / free spirited horse energy without the war undertones. There are a lot of good looking similar ones out there if a more horizontal one would fit better.
