Aside from what I told you at TN...
#1 - Honestly is no good because of the grass as Kerbouchard said. It's completely covering your son, which is the subject and takes away from the image.
#2 - Again I agree with Kerbouchard about the background. You could also stand for some fill flash, but I'm not sure if you can control that on your camera. Look into getting (or making) a couple reflectors that you can use. I'm also not a fan of the framing in this one. He's dead center, which is uninteresting, and the bar your shooting through cuts off his feet from his body which is sort of awkward. If those two front bars weren't there it wouldn't be as bad, but as it stands they're distracting.
#3 - With Kerbouchard again (I should have just quoted you.

). This is the best of the 3... but his eyes are closed because of the sun. You cut off his shoe, he's dead center again, and those blurry pieces of grass sticking up on the right side of the frame are distracting.
#4 - He's centered again... *and* covered by grass again... *and* too small in the frame, in my opinion.
This is what I meant about composition when I was talking to you at TN. I know you don't have a DSLR right now, but you can keep shooting with the camera you've got and practice the things that Kerbouchard and I have mentioned. Research and learn more about composition. Look up the Rule of Thirds. Look at other people's threads here and critique them (even if it's to yourself) and see what others are saying about it and if you can see the same things they're picking out, or even if some of their critique matched yours.
It's a giant learning process, haha.
I know you had asked about starting a business at TN, and in all honesty... you're not ready for that. I know that you said that people tell you your good, but like I said, family and friends are unintentional liers. Their opinions are not to be trusted, haha.
Does that mean you'll NEVER get there? Absolutely not. It just means that you have get the basics down, work hard, and keep learning.
We all had to start somewhere. :sillysmi:
