well, you already know that i personally prefer more DOF in baby pictures, so i wont linger on that point.
I think #4 and #5 are the strongest.
#1 is really fine, but i like more DOF in the horizontal (ish) shots so there's more than just the babys face in focus where all or most of the baby is visible. This is just a personal preference.
#2 is nice, but i think you should have either pulled back a little, or down more and gotten the rest of the baby in the shot at the expense of some of the space at the top.
#3 i would have loved with more DOF. (I know I know...im such a DOF whore) BUT! i find the baby's OOF left hand distracting in that shot. (and maybe the OOF baby blanket trail) i think bringing it IN focus would have looked a little better.
#4 is a great shot. just enough DOF for the horizontal baby to be in focus, while making the background OOF.
#5 is also great. i think i am seeing a hair OOF at the babys feet. maybe motion blur? or just the edge of the DOF? either way, I like this one.
Overall this is a really nice set. I like the lighting on all of them, and I like the contrast levels. Bright is a good look for baby. very nicely done!
