A quick note about this one (http://www.flickr.com/photos/59904248@N07/9308634312/in/set-72157634675000849/) from your critique group on Flickr. It has several problems but the one I wanted to comment on was her left sleeve. It looks like it is just hanging there and except that I see a hand in her lap, I would think that arm was absent. The way some fabrics hang or are coloured can affect the way they look in a photo. Doing something different with her arms, hands on hips perhaps, might give a better result with that top.
Looking at your latest shoot, for me, the brightest part of the first photo, http://www.flickr.com/photos/59904248@N07/9308634312/in/set-72157634675000849/, is the left side of the log and her right foot/leg. That drags my eye down there instead of being on her face.
Generally your white balance is not consistent, still. I am trying to decide if her top is black as it appears in some shots or navy blue as it seems in others. Either way, she would be a good candidate for mom to run a lint roller over her top before shooting. There seems to be lots of debris on her top. There also appears to be a lot of colour noise, which is a bit of a surprise since you are using lighting.
Looking at (http://crash1976.smugmug.com/Clients/Russell/i-fs9CN2x/O) in original size, which fills my smaller monitor with just her face, her eyelashes look good but there is no texture on her cheek or chin. Did you smooth her skin? I would remove pimples and eye bags but for someone her age, unless she had some obvious temporary feature, like a scratch, I would not be inclined to do any work on her skin. It’s not necessary and seeing pores avoids the plastic look. Looking at another, I see she naturally has really smooth skin!
In http://crash1976.smugmug.com/Clients/Russell/i-rqbr475/A, her left cheek is way too hot. Full size, her eye fills my small monitor! I can see the little hairs on her skin. Backed off, her skin looks smoothed.
You still have a couple of B&W in there, white balance needs work, lighting needs work. Little kids can really be a handful. I like that gallery much better than the wedding gallery.
