These shots, as far as I can tell, are quite easy to do:
1. With a lens with a large enough aperture so you can get some bokeh
2. With any number of software filters out there (take your pic which, but I'm pretty sure I'm seeing some Nik Color Efex)
3. With a full frame camera capable of good low iso performance
Take those three elements, and you can recreate any of those pics.
But, seriously, sparky is right. You should seek inspiration from others' styles, not try to copy.
It's one thing to say "hey, that's a cool technique, let's try it!"
Completely another to try to get the EXACT pic.
And looking at these pics, frankly they're not really so spectacular I say "Oh I want that in my portfolio!"
In quite a few shots I see white balance issues, focusing issues, or just in general composition issues.
For instance, take this one:

The colors are all off (whitebalance issue) and it looks like they used a wide angle lens so her face is distorted.
Seriously do you want to do this?!?!
You can see some nice technique on some of the photos... For instance if you look at the below shot you'll see a nice use of shadows. I like the texture created by the stripes of the fire escape

But if I were you I wouldn't want to create THIS shot, I'd go out and play with shadows. Take pictures of models with various shadows coming over them. See what you get.
But looking at some of the shots, I don't see anything special. For instance if you look at this shot, there's nothing special at all. It's just a normal shot, maybe with a speedlight, but really what is special?

Some stuff is just techniques you maybe need to learn. This is for instance an example of "light painting"

Also, this is an example of details extractor or similar filter to give the photos more texture:

Google Nik's software's Color Efex... You can play with different filters and see the effects they have...
The key is to play a lot and then learn what different techniques do. Then you'll be able to look at a scene and say "wow, what if I do _______"
So, all in all, these photos are not special if you just have the equiptment, the know how, and a good place to shoot. Indeed, I bet there are some people on this forum who could do better...
You just need to try learning as much as you can (and unfortunately theres a lot to learn so it may take time). Just play around, experiment, and HAVE FUN.
Then at some point you'll start to see how to make some shots, and hopefully get to the point where you have your own style.
Good luck
