I prefer not to do baby portraits because

1) they do not undrestand direction
2) they are moody
3) parents are usually scared of "bright lights" ruining their baby's vision

You did a fine job. When it comes to the baby portrait genre, I find that many pleasing baby portraits are more a product of photoshop treatment than of a specific lighting style.

I'd suggest trying a black & white, high key, or sepia/antique conversion to images 5256 & 5237 especially. As you're starting with a technically superior image, I think the result could be even better than what I'm accustomed to seeing.
