For first attempt, not bad at all.
Good points: Cute model, nice expression, composition is pretty good, nicely lit, the toning is good.
Now, for the bad points: just 2 from me.
1) Selective colour for me is a no, no. It's a personal opinion, of course, but it's been done to death in the last decade. Another one of my pet hates. The shot itself is fine without the gimmicks. Keep it simple.
2) Soft focus has already been mentioned. Next time select single focus point, and focus on the eye before recomposing. If you do it quick enough before the model moves, you'll get it right every time.
Keep going, and have fun.
