Portrait pictures, looking for critique and touchup ideas

I took some shots of my sister and its mainly the kind of pictures that I take, I am looking for a few things here.

1. Things that I can do to improve the pic when it was taken.
   
2. Touchup ideas which are easy and straight forward (no major surgery please )
   
3. Exposure especially with the water, underexposing will make my subject darker.
   
4. AWB, I used a custom white exposure. I wonder if i done it correctly.

I agree completely!! The only reason I'd ever use manual is if I was doing macro photography or video. Otherwise, even for portraits, manual focus is not useful.

Pretty subject. White balance looks OK. Exposure is spot on in the first one, but she's out of focus. Why manual?

Your focus is good on the second and third. They're overexposed, but not by much. Her top is black, like in the first one, yes? Make it so. A vertical composition would be more appropriate on all of them I think.

Regarding #1...nothing's wrong with using manual focus; perhaps you need to make a dioptric adjustment.

Have you had your eyesight checked recently?

I will check the dioptric adjustment again lol , but I'm sure I didnt mess around with them.

I agree with the others with auto focus. 3. was right on, always expose for your subject.
