A bit to bright from my point of view, clever thought and beautiful collection;-) But could be maybe better if not taken so much from the top and having it a bit darker.
Cute idea. I have some dolls like this, too. Because of the perspective the smaller ones look farther away from each other than the larger ones... I might have tried to compensate a little. I'm also not a huge fan of the background (concrete?).
i like the concept and the framing of this picture alot but i would have put more consideration into the background of your shot. the extreme light i think is too harsh for this shot
