Not that good? These are awesome! The perspective is great, and the angle is awesome. I really like it, like alot. I personally like the first one the best though
Compositionally I think this is a pretty good photo. I like how you haven't photographed it straight on but from a slight angle. It allows me to see more of the patterns on the gate and the stairs behind shrouded in shadow, which makes the image much more interesting than had you only taken a photo of the letter box. However I think you could've benefited from moving the framing down a little bit because you kind of cut off a little of the bottom right of the letter box and have a bit too much dead space above the letter box.
Editing wise I'm not entirely sure why you made the letter box yellow. I assume it has something to do with your story, which I haven't read so sorry for that. I'm not really a big fan of editing photos, I tend to leave mine alone but I'm sure you have your reasons for doing it. I think in the edited version the thing that bothers me the most is the bit under the letter box. It's kind of distracting to the eye and looks like a mistake, even if you meant for it to be like that. I would just be careful that you don't over edit because some of your photo has started to become pixelated.
It's definitely interesting though and perhaps I should read your story to get a better understanding of the picture! Keep taking photos and keep posting them. I'd like to see more.
