This is a lamp that's on the wall in my bedroom -- it's from the children's section at Ikea! Was more interesting to me than the "adult" light options available to be purchased that day. =)
If this is a nightlight I like it. Otherwise, I can't connect the object to an everyday something that I recognize. So I have to go 6, just because it is a nice image.
I like the color combo of blue and yellow, they go together well. I also like the negative space on the left - which furthers the starry night theme. The one light being a bright star shape is cute too. The shadows are a little off, but nothing you could do to avoid those and I dont think they distract too much. I like it.
