I liked the Jeweler (man in watch store). A very nice image. Good composition and use of the light surroundings. Nice exposure. Etc.. What most consider an "environmental portrait." Better than most would make. Well done.
What to change?
My Simple Suggestion: you are the one in control of the composition...make sure you watch out for hands/limbs that leave the frame and take the viewer's eye with it.
Second image I liked was the "boy on bike."
Just like it. Just as it is. Maybe because I used to like to ride a lot when much younger (his age).
Some people will "rag" you on using a subject in the middle of a square frame. "Centered" is often denounced. I don't mind. I like it.
Tyler, it's good to see the colour of the places you visited. Here's a few impressions of your series:
#1 The man looks interesting, but looks like it needs more contrast, sharpening or something to liven it up. Most of all it needs a few steps forward for him to fill the frame. Controlling the background may have been hard, but note the wall running through his head and the bright boat ( ) behind him.
#2 This guy stands out much better than the last. A shot with the entire arm showing would have improved it.
#3 This is another one where you could have stepped forward or zoomed in. Ask yourself if the background stuff on left, right, below and above is adding to the picture.
#4 This one is very centered and the brighter foreground is a bit distracting. I'd crop bottom and our right side.
#5 CEntered again, but the real problem with this one is the face is washed out. You must be aware of your backgrounds and get that bright sky out of the picture.
The SP. Nice lighting. Zoom in or crop shots like this where the subject is small and the edges are not interesting.
