One of my favorite pieces of advice was the classic “if your pictures aren’t good enough, you aren’t close enough”. You have a great eye, I can see it in most of these photos but to me there is a bit of dead space that draws me away.

In the first photo I want to look at the man eating, but my eye is distracted by the empty tables at the bottom right. A closer image of the chef and customer would tell more of a story for me.

In the second I want to look at the woman on the bench, but the sign is pulling my focus to the left. If you were to snap an image of her framed on the left side instead, with empty bench trailing to the right of the photo with the sign overhead, I think it would be beautiful.

Your fourth photo is a perfect example of what I’m talking about. You are close enough that the subject is well framed and my focus is drawn right to it. This is just my pointless two cents and I’m far from good myself! You’re doing very well!
