I'd say that's a very successful photo shoot! Nice job (and cute kids)!

Just some observations from an amateur:

The ones that are standouts for me personally are 1, 2, 7, and 8. 1 shows a lot of personality, with a little grin that seems as if it could turn impish. 2, with his soft yet direct look, and graceful tilt of his head, is absolutely perfect. His eyes are the center of attention; couldn't be more charming! I see both of these have the light coming from slightly below, which wouldn't have occurred to me, but works with their young faces. A creative choice that works.

7 has such a nice contemplative look, yet still with that hint of smile. I'd like to see more picture area on the left (or crop the right side); he's looking out of the picture a little too much. And I'd crop the wood at the top; it's attractive but isn't the subject of the picture. Also, did you light him with a reflector? There's a white line through the center of his irises that I'd like to see gone.

I really like the high key feel of 8, and your focus is appropriately on his face and not his arm. Another dreamy look which shows an appealing part of his personality. It might be fun to play around with blurring and lightening everything but his features.

Just my preferences. Very good job on all of these!
