Charlotte,
I'm delighted that you share the joy of family with us. Also, I must commend your B&W work extending tonality all over the gray scale effectively in these three pictures.
I like this new way of you presenting your B&W work. There's real detail even in the dark blacks! You might perhaps pull back the brights with shadow highlight tool or from the RAW file. If you got that, these would be technically better.
Still, for the joy of the children, these pictures can't be better!
Asher
