Well, they are quite random indeed. I really like the third one - very strong facial expression. I'm not a fan of framing though - cutting of the lower part of the face is not something that I'm after. Overally, quite nice portraits, keep them coming
I agree about the crop in the third image - no problem cropping into the forehead, but if you do I'd like to see the rest of the face. Otherwise, a random set but a nice one.
