I agree that the faces on the second two are hot.
The first one is pretty close to me. May dial down the power of the flash a little (and I mean a very little, like from 1/2 to 1/4)
Thats one cute baby.
For me, the left side of the sheet is distracting. If it was all white I think it would play better with this style. I like the picture soft. Also its kind of bright lol. IDK though lol I'm just a noob
But the wb isn't right, that bg is pure white.
Background are only pure white.. if you light them to be pure white.... you can't base your subject exposure on what you want your background to be.... lol!
Did you light the background separately?
