I think you got pretty um... insulted for what seems to me like a decent picture. I really like the way you framed this. And the colors are good too. But the comments are correct, in that, the focus isn't the best. Keep working on it an perhaps invest in a better camera :] hehe jk. (but not really)
The focus is blurry and messy, the colors lack that vivid boldness, and it looks like they took the picture by putting the camera above their own heads.
Great framing and close crop. Lighting and softness work well, although it could be a tad sharper. I especially like the expression from the girl on the right. Nice colors too.
