Rainbows <3
I like seeing the rainbow in the background appearing after the storm has calmed while the sun begins to come out and shine down on her bright cheery face. I like how you went on this piece, it just looks really nice.
The background has a rainbow in it, need I say more? :P
Then she has a rainbow ribbon in her hair which looks cute in her brown hair by the way, really brightens things up a whole lot more than usual. The heels are also pretty cute as well in my opinion.
Her face has a real jolly expression on it. The wink and open happy mouth make her seem very happy to me. have got to say though, I really like her frilled skirt, it just looks completely adorable and makes her seem like an easy to get along with person as long as you don't hurt her feelings.
The shirt is simplest though, better than nothing at all though. I have to say though, she looks like a pretty nice and happily cute person.
Overall, <3. Nice ID drawing though. :-)
