Despite your apprehension, you managed to capture some excellent shots! Practice makes perfect, right?
@mweich brought up a really good point. Giving yourself permission to take photos (in addition to shop owners' permission) could be a key to your personal development! I think it's cool that you are pushing yourself into slightly uncomfortable territory because that's how we grow.
By the way, have you seen the current #culturevulture challenge (click here) by @eroche?
Your photos are phenomenal, I think you could place or win. Just a friendly idea ☺
Good idea and a big thanks! :D
