I guess I'll be the honest one with c&c (or the one that knows).
1, 4, and 9 are too bad overexposed. Would have been better to drop exposure down and use a slight amount of fill flash. By slight I mean, dial it down to around -2 Flash Comp give or take a bit.
In general, be careful not to go overboard with sharpening the eyes. Number
2 and number 5 (moreso in 2), the eyes are just plain out of focus and sharpening them in post just makes them look odd since they aren't in focus in the first place.....almost inhances the blur.
Some of them have really flat lighting (particularly 3 and 5)...not much you can do with that unless you want to get a new flash and/or experiment with some off camera flash (not as easy with your D40 as with a Nikon model that has CLS).
Of this bunch, number 6 is really great. Wonderful lighting and focus is spot on...eye sharpening is just right too. Number 8 isn't that bad either...just a little too much flash causing her to get washed out and focus was off just a hair it looks like (on my screen at least).
Hope that helps and keep shooting.
As for the people who responded with "there's nothing to critique" or "they all look pretty good"...seriously, stop posting in c&c threads. You prove by your comments that you are obviously nowhere near qualified to give advice in a thread asking for c&c.
Oh, and in the future, try to not post so many pictures in one thread. It makes it really hard to give c&c. Most say limit to 3...I personally have no problem with about 5-6 photos but more than that and it's a pain scrolling back up to see which number it was. I wasn't going to reply because of that (and others won't as well), but I remembered that I gave you c&c once before and you were very appreciated despite my brutal honesty...that's why I took the time in this thread.
