Ahh, Cassidy is a little star mate. What a beautiful set. I think we sometimes forget the beauty of natural light and you're showing it off really well.
Got to love a good bit of natural light! Nice catchlights in the first two. Only real crit (and this is something I'm guilty of) is watch the backgrounds in terms of the blocks/angles of colour. By no means a deal breaker though!
Good stuff
