Nicely done! Attractive subject, soft and smooth, pensive look. Focus is just right, I think, and the colors. The rubber band on her wrist is a down-to-earth touch too; reminds me of a friend who does that.
Interesting the way the "dots" can be seen as floating freely like balloons. And the eye picks up other round things in the image... nice zig-zags too!
anyway - perfect!!
