Hi, congrats on having a go at doing some baby shoots (possibly the hardest subject to keep still for photos
)
I think the pictures are nice and well composed, but they seem abit overexposed. The first one looks really nice in Sepia, but it looks like the flash might have been on full - perhaps try using a diffuser if this was the case.
The background in the last picture is abit harsh, and washes out the colours of the suits they're wearing, maybe a change of clothes, or a not so white background perhaps. Skin tones can be improved in Photoshop etc, and might be worth having a go at this on the colour ones.
