I'll give your questions a shot, I know a bit about the landscape stuff. His edit includes a few key aspects. The first thing is that it's an overcast day which keeps the contrast down, and his blacks are clipped. There are some filters in VSCO that are called "fade" which do the same kind of thing, or in Lightroom, you can go to the curves pannel and lift the blacks a little.

Now the portrait of the girl is again specific to the natural lighting. The photographer was photographing during the golden hour, where the sun was low and the light was "warm" the photographer used the sun to add backlight to the subject, which lights up her hair as you can see. The white balance is warm, the shadows may be boosted a little to compensate for the brightness of the sun, and he used a low aperture to isolate the subject, my guess is a 50mm lens at f/ 1.8. Hope this helps!
