Go for it.

Thanks for replying, Benji. Next time, I'll adjust the main and soften it a bit. You're right about the shadows.

That is his only smile. She said, "you're going to hate his smile" when they first walked in, ha ha.

I must admit a very strong disappointment to the lack of comments my image has received.

Thanks, Mike. Instead of F/2, what should I have used for this couple? I'd also love to know what people use for large groups, as I might have one of those coming up.

I didn't notice before, but just did, that he has a shirt fold down the center of his sweater. Now that I see it, it's bugging the heck out of me, ha ha.

Hi Marian
Sorry I didn't comment earlier.  Where the cord connects to my monitor has a problem and images were looking smeared, it's jerry-rigged for the time being until I can get another monitor (or cord, if that's an option).  I haven't been commenting on images for that reason.  I know it's frustrating to not get any feedback, the last image I put in this session got one critique.  So I feel ya, and I wasn't ignoring you.

First off, for my studio work I use F8 most of the time.  My lens seems nice and sharp there and I don't have to worry about things going out of focus, but because of my set design and the type of work I do I am not trying to blur the background necessarily, so take that for what it's worth. 

I think your pose could be improved.  It's not a pleasing composition, they are just both in the picture.  I would have turned her back to his front, which would have hidden the line that you just now noticed (that I had to look twice to see).  Although you don't have to go that route with posing couples.  It just sorta looks like she is leaning to get into the picture and his arm is a bit awkward. 
The exposure is great.  I think the lighting could be improved.  The lighting is nice on his face, but the pattern on her face isn't great.  That's also why I mentioned turning her away from him, then she would have the same lighting on her face.  Unfortunately I am not experienced enough to know how to light a couple that are sorta turned toward each other.  I would just go for flat lighting...  Your lighting is fairly flat so the problem isn't huge.
Perhaps we need a more experienced lighting pro around here to demonstrate how to light a couple posed this way.  That way we could both learn.
The other thing I notice is that the background is so bright that the light is reflecting back onto her hair.  At least I think that is what is happening.  Their clothing is dark and in traditional portrature you should have gone with a low-key background and lighting, but I see this rule broken so often that I am used to it, I only noticed for critiquing purposes and thought I would mention it in case you are trying to be traditional (although that's not your style, you are more modern).

Anyway, I feel like I nitpicked your image and that it will come across as harsh, but I really think you are doing a good job and are well on your way.  I just wanted to point out things that will hopefully help you improve because I know your potential is so great.  I have seen your style really developing and your skill level going up and up.  You are doing so well!
