I'm hoping I can get some advice here.
I'm working with a D7100 / Sigma 17-50mm f/2.8 EX OS DC combination and I'm having difficulty getting sharp images all the time.
I was beginning to think it might be the lens, but I know better - because occasionally I get a great shot that's tack sharp and I know my skills as a photographer have some room to improve. I seem to miss a lot of shots that aren't tack sharp - I mean, they're acceptably sharp to view on the web shrunk down, but when I get to a decent size view or print size I can tell that eyes are not sharp.
I've done the "dot tune" method on this lens/body combo. It's not exclusive to this lens, but this is my main lens I shoot with.
For example, I have these few images:

I'm unsure as to why they're not coming out sharp.
However, I do get a few images that come out pretty good:

I have a feeling it's because I'm shooting wide open, but in most cases, neither face is sharp.
Help?
