hi bric,
i think that if i were the client i'd be pleased. you did a nice job of cropping, red-eye removal and replacing the background. you kept the integrity of the image there and really brought the baby out!
at the risk of going past what's needed and wanted by the client, and going into nit-picking mode, i'd say the face could be just a tiny bit sharper, the outline of the head is just a tiny bit on the side of 'looks pasted in', and the contrast could be just a tiny bit more for a little punch.
i've atttached an image to show what i mean. it's about a 10 minute job to do the things i mentioned. i used a normal global sharpen twice and one light pass over the eyes with the sharpen brush. i ran a softness brush around the perimeter of the head where it's against the background and i added an adjustment layer of contrast/lighten at 0 lighten/13 contrast. i also did just a tiny bit of 'push' inside the eyes just to smooth up a couple pixels.
but like i say, this is in nit-pick mode, so disregard everything if the client likes what you did
