It is a bit small - but then I make larger quilts so they can use it up to 5 or 6 years. Maybe you could find fabric to compliment the fabric you used to frame it.
On the other hand, since it is a little girl, when it is finished being a quilt for her, it will be perfect as a quilt for her dolls. When my mother passed away I found a yard of fabric that had a very cute jungle theme. We have no idea where it came from. It was just one yard, and she quit sewing more than 30 years before she passed away. Since my niece was expecting at the time, I backed it with a very soft flannel, quilted it, then put a binding on it. She had twins a month after my mom passed a boy and a girl. That was 6 years ago and the blanket wraps around my niece's favorite doll.
