I'm no professional, but here is what I would of done.
Photo 1-
- Had subject stand with both feet on the ground, one forward more then the other. Then had subject put her weight on her back foot, making her appear slimmer.
- Had her lower her arms so that she could bend them & create angles. Angles make for a more interesting portrait.
-Watched the way the clothing lays on her body-the wrinkles in the jeans by the crotch, bust, etc. isn't very flattering and call attention to those places.
I would of also tried shooting a foot or so higher then the subject to put more emphasis on her face and eyes, and less on the rest of her body.
Photo 2-
-I would've had her turn towards me just a bit more, so that the eye furthest from the camera didn't look crossed. Otherwise, it's a lovely portrait!
Photo 3-
-Once again, I would've checked how his clothing lays on his body,he looks sloppy. Granted, I know there is only so much one can do with a 2 year old!
-Changed camera angle or how the child was sitting so that the shoes didn't end up in the photo the way they did. I find them distracting!
Other then those things, I wouldn't change anything!
