This is adorable and hilarious content-wise, in addition to being lovely to look at. You really captured them, and their expressions are the best! Maybe this is how things could have been, if their father was not an evil vengence bent jerk.
WHY THEY HAVE TO DIEEEEEEE?????  Noatak and Tarrlok show me most affection between brothers in one episode than Mako and Bolin in all the season! They was amazing, genial characters with a sad and beautiful history, I will miss them in the next season! ;___; *cries a river*
There's something original and serious in the way you draw Noatak. It makes him very handsome. And then there's another unique way in the way you draw Tarrlok that makes him seem like the happy kid he once was!XD
I love it both ways, and I agree your style looks better flat coloured/
