Some of the comments seem a bit harsh.
My two-cents (and worth every penny): Sort of depends on the look you are going for here: documentary, portrait or glamour.
Very hard for me to separate my personal style when critiquing others. I personally tend to "clean up" almost every portrait I shoot. Admittedly, I'm sort of a wimp, but I tend to make portraits that I think will reflect how we see the person more than how they actually look.
When you see a person, you are not seeing them frozen in time, but as a human being that moves, talks, reacts, etc. As such, we don't usually focus on minor imperfections (a zit, a mole, a wrinkle, etc.) because the person is moving and we are reacting to them and not studying them. But if we freeze them in time, those imperfections can be distracting.
For ordinary portraits, I tend to reduce the skin imperfections (but not remove them entirely, especially if they are a permanent feature -- a mole for example. If it's a temporary imperfection like a pimple, I have no problem erasing it).
I personally like either lighting that give a lot of modeling and shows off the character of the face or 'glamour' lighting that can tend to wash out details but look very flattering. I'm not much for "somewhere in-between" but again that's a personal preference.
Also, I like a longer lens in order to compress facial features so noses don't look quite as big. Again, it's that frozen in time problem. When you meet someone and talk to them, you don't really study their features. But, in a still photo, you have lots of time to do that.
This is a nice environmental portrait that I think works in either format. My personal style would be to up the saturation a bit in color and up the contrast a bit in either black and white or color to give it a touch more drama.

How do you convert to BW?
I use Silver Efex Pro.
If you really want to learn B&W conversions try Vincent Versace's "From Oz to Kansas." I think he goes a bit overboard and makes too much of some fairly insignificant little differences, but it's probably good to learn the techniques and pick and choose what you want.
Scott Kelby's books also offer some simple Black and White conversions.
At a mininum, add a adjustment layer using the "gradient map" option. Then you can play around with a levels adjustment (another layer) to get the effect you are after.
