This is my first time officially critiquing. *crosses fingers* Here we go!
In general, I love it to pieces (so going in my favorites). The concept, the colors, the characters and their actions, all of it is great. It really caught my eye.
1)I love how you've caught each of their personalities. Sakura is being her usual chirpy self, Naruto is himself, and Sai is his own sweet, quiet, artist (yet you can tell he's with the others still).
2)I like how it's those three. They seem to have a good friendship going and this really shows it (to me).
1)The colors seems a bit muted (for lack of a better word). It doesn't make the picture bad or anything. I just think if the colors were more vibrant that the picture would pop out more.
All in all, a great picture. Thanks for sharing it on DA with us.
