Ashely, there really is nothing wrong with them...any of them
Is 5.0 the lowest aperture on your lens?
1- I like your aperture because this allows the water to be in focus along with the feet.
2- Because you are closer in, the parents hand is out of focus, putting the baby's hand in focus, which I like.
3- Colors look great. It appears to be slightly out of focus...probably because the shutter speed is on the slow side and your subjec is a baby who never hold still! lol. If you were able to lower your aperture, you could increase your shutter speed.
4- LOVE this one. It almost appears that it was taken with a wide angle lens.
5- LOVE this one. I also like what you did with the saturation. Very "child-like"
6- Looks a tad underexposed. I would have slowed your shutter speed just a tad or lowered your aperture.
What ISO were you using for all of these?
