It is hard to hear constructive criticism. We see how far we have come from when we first started photographing. We look at others work and see how far we still have to go.
I would say that the images are, how i would compare them due to my experiences. Above the standard working out of my home photo business, but under the "i have my own studio" photographer.
First the bad.
As many have pointed out the dappled lighting in 1,2,3, and the last image.
Missed focus on the boy in 6 and on the mom in 7 unless this is jpeg compression on the mom.
CA, chromatic aberration in 2 and possibly 5.
Be careful about over processing the eyes. It looks like you were trying to increase the exposure/contrast a bit much trying to brighten the eyes. More noticeable on the dad, unless his hazel eyes are just that intense. Also the last image the eyes are too white and sharpened/clarity imho. I have a bigger issue with this then most people. Due to the dappled lighting one eye is brighter then the other on the same person on a lot of the images.The way to fix the eyes in camera is to better control the light reflector/off camera flash or covered shade.
The good.
I think the posing and framing/composition is done well for the most part.
You caught some genuine smiles and moments. This alone is more than many photographers can do. The dads smile is fine to me, it looks to be just who he is.
I think that with just a little more control of the lighting, you can really be a stand out photographer in your community, but that you are currently better then the average guy in your community.
