First baby session
Great moments captured in all three. Exceptional moments! I would crop the first two to eliminate as much of the blackness as possible. I try to be open to other people's aesthetic, but going wider to include the dark area pushes the subjects away and darkens the feel of the images. Fortunately cropping to bring the subjects forward so they fill the frame is an easy edit. On the third one, brighten the hand reaching out. It's an important part of the action and enhances the baby's curiosity.
These are special images. Nice job,
