First off, it's none of your business if I charged or not. For all you know, it could be portfolio work. Second, the middle one is my daughter which I took over two years ago. Third, my clients were perfectly happy and ecstatic which is what counts! And, last but not least, it's amazing at how rude some people can be when they believe they are the only one who is right. I don't mind critique, but to be so arrogant is outright horrid!
The best learned lessons are learned in blood.
What I'm about to say, I mean constructively. However, I have a feeling you are going to take it personally. These are obviously professional and paid photographs, except for your daughter. The easiest way to tell this is by your reply.
That being said, they aren't very good. Mind you, I'm not saying my portrait work is any better... but I'm not charging people for mine yet. I won't charge until I feel that my work is competitive enough with others work to charge for it.
However, your reply towards others is a bit repulsive. It makes me not want to critique anymore. His reply was blunt, yes; but attacking? No.
Simply put, you just didn't like the fact that someone expressed that your work was "sub-par."
Now, if you want to be critiqued on the individual photos, I can do that for you, too.
1. He/she/it looks pissed off. There is emotion, but not the right emotion. The pose looks like a sad attempt for an entrance into Vogue magazine, the lighting is harsh, as with the shadows.
2. Underexposed, white balance is off, and zero processing was done to this image to correct either. It's noisy, and her eyes do not stand out. Lastly, although your daughter is very pretty, her arm pits are not. Toss that pose altogether. This should be the last time you ever use it. It's terrible.
3. The child would have been better off not smiling. Tones don't look bad, but the pose isn't that great either. He's not really expressing how much of a "fun time at play" he's actually having.
