well.. I must say i reeaaalllly love it.
I've never made any baby-pictures myself, but this stimulates me to do it!
i like the first one the best, tho only one eye is sharp. i think 2 sharp eyes would be better, but. i don't know what camera you have and what possibilities it has.
(me myself, am actually a camera-newbie)
one tip about the composition:
when photographing people, try to get a clear space at the spot their looking to.
in this case it should be left.. cuase it gives you some more depth, and you're wondering where the kid is looking towards.
you did that better in the second shot.
I read this here in the blog, although i cant find the article anymore...
maybe anybody else knows?
also, with a little color balance in photoshop you can make the skin less-blue to make the eyes stand out, but i dont know if you have the program.
nonetheless, as I said, I totally love the picture.
BTW: is it ok if i manipulate your photograph to show you what i mean?
