Certainly the following is all opinion.
You have some nice environmental portraits here. The poses and compositions are pleasing if rather dated. The images are kind of small here but....
#1 is underexposed but the underexposure is fairly easy to fix post process, but it is always easiest to cover most of your exposure and compositional bases in the camera. I would crop a bit off the top. I would also do a version as a head and shoulders crop in a 4:5 aspect ratio (8x10).
#2 could have benefited from fill light to balance the bright background sky. If you have a new enough release of Photoshop you can open the image in ACR and adjust the Fill slider to accomplish that. It's unfortunate you cut off his lower leg. I feel there is a little to much space on the left so you might want to try some differnt crops on this one too.
#3 is also looks a bit underexposed and he is missing part of his hand and his elbow is out of frame. This has more of a candid feel rather than a portrait. The surf line? rocks, whatever it is there in the upper left corner could easily be a distraction from your subjects.
When it comes to portraiture, the devil is in the details....
I would say your 'eye' is adequet for now, but I can imagine the growth attainable with some thought, research and practice. :thumbup:
