Personally, I don't think this photo needs a lot of explanation. The words fit with the photo, I think, because the person walking alone signifies how no one knows me and everything about me. Not even my best friend knows everything about me. I chose the the font because it seems simple, and the same goes for the six words. The colour I chose has the same reasoning. Plus I like this shade of pink. I didn't add any effects on the picture because with the reasoning above, it's simple enough that it doesn't need to be changed.
