The Gaang

I think you've a great own style.
I know it is very hard to create your own style so with that you've already reached a lot ^^.
You made many great little details and the white line around the characters makes them pop out even better.
The only thing i am not sure about is Zuko's leg angle it looks a bit strange maybe it would be better when you made his right leg point to the front instead of pointing to the right but that's just a little detail right? ^^
Oh yes and i really like their face expressions expacially Aang's face <img src="e.deviantart.net/emoticons/s/s…" width="15" height="15" alt="" data-embed-type="emoticon" data-embed-id="391" title=" (Smile)"/>
And you have used a great title for your beautiful artpiece.

I hope this will help you improve your work.
