The lighting is too straight on so there's no nice shadows. We get used to sun and ceiling light coming from above so people appear unnatural when lit low from the front and sides.
That Soft focus 'thing' is horrible in the first shot. It's almost offensive because everyone including the subject knows the main purpose for it.
Max bloom is right with the cropping, the images feel too claustrophobic.
He steals the show a little, I'm not sure if you want this, it's not necessarily a bad thing.
Your depth of field is too low, low dof works fine in portraits unless something like what has happened in your pictures occurs where part of the face is focused but blur appears on the nose. Always focus on the eyes if possible and allow for a high enough aperture to get the nose in, the ears and hair usually look okay falling in to blur.
"The problem is that I can't see the green or the light spots. So, I guess that I also need to learn to see what others see. But, that's how we grow right?"
The skin tones are NOT wrong as far as I can tell. They appear wrong because you did not convert them to the srgb colour space before uploading them to the net. Most browsers will display photo's with the adobe 1998 colour space with out of gamut colours, as is the case with yours. If you need help with this feel free to ask. Lets say the colours aren't perfect. Edit them until satisfied but remember to still convert the profile to Srgb before going on to the web or sending them to an amateur printer. Adobe 1989 is a good colour space to use with a decent printer at home or away or when viewing to a client in your post processing program.
I feel mean saying all these things but hopefully I'm being constructive and positive. I know how it is in a shoot and most things are forgotten, it's all well and good analysing a picture when it's too late, I do it to myself far too frequently.
