humm...well I am self teaching photoshop...and I guess i want to know if I am headed in the right direction or totally off base... I shall take from your comment that I shouldn't quit my day job.. Im just learning so I suppost looking for c&c.
The first one of the last set is too dark, and the second one of the last set is too bright, just under and over exposure. But don't get me wrong, sometimes those work, like underexposure if you're trying to go for a moody look, or overexposure if you're trying to go for a clean "heavenly" look (think models who are just doing skin commercials in black and white, thats the best way i can describe it) but for children i think you should be able to see all their details and see how cute they are!
Just a reply to your message... i appreciate your comment... im still learning.... the day was bright and the second one in the second set was straight out of camera... and I was attempting to take it from over exposed to properly exposed... I missed the mark..LOL back to the drawing board!
You need to work on composition, framing, and other basics before you worry about Photoshop. I'm not saying that in direct critique of your photos here, but in general: photoshop can only help make good photos better. It can't do all of the work for you. I'd go work more on the basics, and don't worry about post-processing until you can get a great photo straight out of the camera first.
