This is a really great picture! But....
I would love to see pictures of other members and allies, grown up to around this age of 20's or 30's, too.
Suki joined them near the end of the show, and although she returned to her Kyoshi warriors, she really helped them throughout the show, especially in Sozin's Comet. Mai helped Zuko escape from the Boiling Rock prison, and Ty Lee joined Suki's Kyoshi warriors at the end.
And although Azula was not really a member in The Promise Part 3 and ran away, it would still be interesting to see what she looks like at around this age, if she is not trapped in the Spirit World like Zhao.
Please, artists, give us a great picture of Suki, Mai, and Ty Lee, like the picture above!!!
