SKin tone and exposure C&C

[Rgollar]

I know these pictures are not compose well. I am just trying to get an idea if the skin tones are correct looking and if the exposure look ok? I by no means want to be a pro just a hobbyist, but still want acceptable pictures for myself. Thanks in advance.

On my screen the exposure looks good on both. The first the skin tone looks good to me, the 2nd baby looks a lil purple ish or something? I'm no pro.. and not on a calibrated monitor, but aside from the purplish going on in 2, I think they look okay.
