if you’re not already doing so, shoot raw & edit in lightroom instead of letting the camera process the photo for you. You have FAR more control over your work.
There is a time and place for off-angle horizon line shots, but I’m not sure portraits of children is where is works best. Instead, watch a few videos on cropping using Golden Ratio or Rule of Thirds or Fibonacci Spiral to really draw the viewer in.
Thanks for your feedback. I know I need to shoot raw. Last week I did my first session in raw.  I just watched a tutorial on kelbytraining on how to process raw images.  I have been using LR for years but never realized I already have the tools in LR to do just that. I will look into the cropping videos!
Thank you. You are right, facebook is pretty bad. I also have a website but facebook is where my clients are, and where they want to see their images. It also generates a lot of business for me. I dont get as much traffic on my website. I know it is because I dont work on it very often. Maybe I should have a flicker account also?
