These are some shots I've taken of my 13 month old son with my Nikon point & shoot and a little editing after. (excuse the drool and wet shirt he's teething)
Certainly I, as any parent can, understand that. But it's important that if you want to take a photo that people other than you and your family can appreciate, that you have a pile of non-drooly shirts available at the shoot
well, then. next time make sure to have a stack of shirts!! people often get so wrapped up in lighting and exposure, they miss important details like this.
In fact, I think the technical side of things is the easier part of portraiture.
Yep, these look like snapshots on a point and shoot camera with inadequate lighting. Are you currently reading any books on photography, or what are you working on at the moment?
Move him further away from the background. The light on his face looks harsh, perhaps exacerbated by the light reflecting off the drool. Did you use pop up flash for these?
More or less the same thing as pop up flash (any flash that's on the camera). Get more distance between him and the camera. That will help with the harsh-ness on a P&S.
