You actually make money off that portfolio?
Regardless of what camera you use, anybody with a snapshot camera and a PP program could get better results. Your compositions aren't even attractive.
The only shot, mildly approaching professional is the shot of the train tracks where you've actually taken advantage of your camera.
I would say you're cheating people out of money just by charging them to take photos they could take themselves...without any photography training or an expensive camera.
The "portrait setup" of your son, looks like an over exposed snapshot of you just pointing and shooting, without any though to composition, settings or exposure.
You're lazy and a cheat, and it shows in the work you produce.
