I love the background. Maybe the character and doll thing should take up more space. The doll could do more shading. Overall it looks very attractive. Nice idea and it looks good. The background is very affective and I see it is one of your strengths. Carry on improving! I might say that it looks a bit of a jump in colour combinations as the background is nice and bright and not SO SO bright while the characters are quite dull and plain. Next time maybe think more about colour differences.
You owe me a pic for getting u points xD
