Keeping your post to 2-3 pictures usually means that you will get CC on all of them. If you post more, people tend to just pick and choose a few as giving CC on all takes more time.
#2 Seems a little on the blue side and a tad dark, check your white balance and exposure. Interesting composition, although Im not sure I like how you cut off her elbow or the top of his hat. Someone once told me that if you want to cut off body parts, dont do so at the joints (ie neck, elbow, knee, ). The heads are also out of focus when they should be your main focus
#3 Too much dead space up top and his butt is too close to the bottom of the frame. Lowering the camera would help with composition on this one. Maybe getting him to angle the fishing rod a bit more up to a more straight angle. And its really not in focus
Overall eyes and faces are the most important thing to get in focus when you are taking a picture. How is your focus system setup in the camera? I assume you are letting the camera chose what to focus on? This sometimes works, but I prefer to set it to only the middle dot as a focus point. I aim it at the persons eyes (or whatever you want in focus), half press the button so it focuses and while still half pressing the button, I move the camera to recompose the shot.
