I really like these. The perspective on the first one is nice and interesting. You did a great job filling the frame with both photos.
One thing I've learned to do when taking portraits is bring the aperture down to f/2.8 with my 50mm lens (it's the only lens I have that can go this wide)... I have opened up my photos too many times to see one or both eyes out of focus because of the narrow depth of field. Also, when taking portraits with more than one person, you have a better chance of both being in focus. The baby's left eye is slightly out of focus in the second photo, but not so much that it's distracting for me.
Just curious... what mode do you shoot in mostly? (Aperture Priority, Shutter Priority or Auto)
