I love this picture, the entire series is actually really beautiful and I hope I can get all of them at one point.  
There is one thing that does irk me though, the "rain" is falling straight down, meaning there's no wind... yet, the girl's hair is blowing as if there was wind (but not the dog's hair?).  I think a couple other pictures in this series have this same "issue", maybe the artist loves how hair looks when it's being moved by the wind?  I avoided the other pictures because of this, was surprised to find out I didn't notice it on this one.  It's not a dealbreaker or anything, just one of those things that sort of bug me some times.
