JerseyJules, while I understand how you feel hurt that you didn't get the response you were thinking you were going to get (praise), you have to understand that this is group of photographers (newbies and seasoned pros) they look at pictures differently than family and friends will. You pictures are wonderful snapshots of your children, you captured wonderful memories. Technically there are more than a few issues, if you are wanting to improve, listen to those that offer help. Do not come off as uppity, snotty or full of oneself because believe me there is always someone here that will knock you down a peg or two.
When I posted my first image here, I thought I rocked the world, I mean why wouldn't I? My family and friends were telling me I was great! Looking back I can't believe I thought I was a "natural" at photography. I've been here over a year, I read a ton, learn even more and post an image for C&C every now and again and you know what? I'm still no where close to being half way as good as I thought I was when I first posted here.
You have cute children, they seem to like being infront of the camera. Use that to your advantage, practice as much as you can. I don't know what your goals with photography are, they might be as simple as mine. To take the best possible family pictures I can or you might be more loafty and have your eyes set on becoming a professional, either way the people on this forum will help you reach those goals. You just have to open yourself up to the help they offer. They might not deliver the message in the nicest way (no sugar coating it) but they will more than willing to guide you in the right direction. You just have to be nicer in your delivery of your questions. No one wants to help a sore apple.
