1st time with collage

I read the tutorial to create the collage in BB. I intended to do the same one but I thought it was a bit boring. Therefore I just read the process to understand then did a new one for me. The Music man is so hot, that's why I did a cool one.
My collage includes 3 images that seem to have the same emotion (downloaded from http://www.sxc.hu/ )
I thought overlay effect is a good way to combine images that have different colors. The small dots snow is also created by another effect.It's not the real snow^^. After finishing, I found that the eyes of the baby girl was black, it made the image not be cool at all. Therefore, I changed them into blue and added a bit snow.
