The dress is real lovely on her. You did a great job on that. I like how you outlined the dress too -- it makes it show out more.
The only thing I find odd about this picture are the hands - but I can't draw hands very well myself; it's something I still struggle with even though I've been drawing for years.
Not that it ruins the picture. I think it's still great otherwise. Keep up the work!
I love the flowers on it. And You did a great job on her hair.
