Well, I think you chose a fine location for your portraits here, but you still haven't composed your pictures to their optimum.
What I think about the first I already expressed in Photo Critique where it also shows (alone), and I am glad to see you tried some of what I said in the second, though you might consider cropping in more from all sides to bring her out more. There's lines that give you some good help for the endeavour!
Photo 3 has the same issues as does #1, again there is that blue thing in the background that invariably attracts my eye and piques my interest to find out what it is ... and if that isn't distracting from your daughter's (?) photo then I don't know what else is... and you can't want that, can you? But there is so much room for cropping, you can still go creative with the image as it is. No problem.
Actually, I quite like the concept of the last almost best of all, if only that sky hadn't been so utterly bland - overcast, and still bright...
Again some cropping could bring out more, place her even further left, i.e. lose some on the left, crop in from above to retain your usual print ratio, and combine portrait with background (would be my idea).
All in all they are a bit flat colour and contrastwise and could do with some play in the levels or the curves (I should ask Mark about the difference between the two, as I don't see any difference in the results, but I fear even now that I might not understand his answer

).
