Well I think they all work really well and you have a good eye for pattern and color.
#1 that is a really beautiful blouse on you and I think colorwise works well with the navy pants and lighter accessories (I like the white watch). I'm not totally sure about the cut of the pants in this outfit but dress trousers are not something I know much about.
#2 Gorgeous! The coral shoes are great next to your bare legs, and that dress is amazing. I think you are dress twins with Janet? I wish I could be a dress triplet...
#3 I like the pattern of the top and of course the white and coral are great. I might try another color pant or skirt if you wanted to do variations on this - I think navy or ink would be a great bold contrast, and a paler tan or off white might work well. I can also see olive or charcoal working - I'm thinking slightly more pale tones or darker tones rather than mid range in general.
#4 I really like the top on you and think it transitions well into the pants. I also like the t-strap shoes, but you could experiment with sharper toe shapes if you wanted to try something different down here.
I always retake my WIW pictures on the weekend because that's when I have a camera, so of course they look a little different :).
