Hi! Your little supermodel is adorable, so you're off to a great start! Here's the two things that immediately came to my mind...
1. When photographing people, it's generally a bad idea to cut them off at a major joint (elbow, wrist, etc...) In this case, you cut the little lady off at the knee, and it brings unnecessary tension to the photo.
2. Your model is little bit too far off center. The extra space on the right side of the photo adds nothing to the overall image.
Thanks for sharing! Keep shooting!
