I do like the first one, I like the pattern the wall corners make behind the man. It's also nice how it gets lighter towards the right.
The third one however, I'm not sure I particularly like. The setting is very good, it looks like a really nice place to photograph. However, I feel that the person there is throwing of the leading lines.
You have the lines created by the pole things in the ground; this fits in nicely with the strong red and the steam which catches the eye. But then the man with his gaze creates a strong leading line going outside the photo, not towards the middle. I feel this makes the shot a little jarring.
Overall though, nice work with the photos and good luck taking shots of people in the future.
