I think the lighting is harsh which makes the skin look blotchy.
Nice compositions though.
Especially in the last one.
I think there is too much white space above his head in the first as well.
lovely kids.
i think your white balance is off slightly, the background doesnt quite look white. and the eyes could do with a little brightening to bring out the brown(i think hacker did a tutorial, "how to make eyes pop") some nice poses and im sure grandma will love em
I am guilty of doing this before, but the catchlights are very square, so the flash is probably too close
