As with other streetscape photos, what is it that captures your eyes? Is it something worth photographing? It doesn't have to carry a message or tell a story, heck it doesn't even have to be interesting to anybody else. Ask yourself, what is this photo to you? You should not be asking if you should have captured this, only you have the answers. Learn to visualise and design your photos and that's when you know how it will turn out, even before you push the button. That's when you know if that shot is worth taken or not. Photography is not about getting a camera out there and hoping for the best.
