VERY nice job smoothing out that paint. Looks like it could be a Mary Kay promotional car!
She's a beautiful young lady, and did a very nice job with that. Keep her building something- cars, planes, ships, figures. Kids don't work enough with their hands anymore and have lost the art of appreciating delayed gratification. Keep her at it, and she can point the way to her school mates and friends that instant satisfaction isn't all that great.
As Rob said, that winning smile says it all. No faking that.
