This illustrates one of the real joys of digital photography, which is the ability to take photographs and then immediately see and share the results. This is just such a moment— sharing a selfie on a day out in Manchester, with friends.
The photograph just captures a moment of joy on the subjects' faces. The background is untidy and, probably, distracting without adding anything of significance. A tighter crop could remove some of the background, but with shots like this, I am always torn between a very tight crop and the context the background brings. The balance is somewhat personal, and I expect others might prefer the crop to be tighter.
