What a pity that the AF slipped to the tree trunk behind the girls in the first. Their expressions are so nice - could have been a very good photo. Sorry to say so, but as it is, it looks like a snapshot...
The second is nice (she is your daughter, isn`t she?), only would I suggest an even tighter crop to leave out most of the background and concentrate on the bikini-girl and her inflatable toy.
The selective colouring in the last is, of course, something that I can't do myself, at all. Which is why I shall for all times find it very interesting.
