In the context you've given, this isn't really a lifestyle shot. To quote:
"[SIZE=-1]Lifestyle is a way of living based on identifiable patterns of behaviour based on an individual’s choice, influenced by the individual’s personal characteristics, their social interactions, and socioeconomic and environmental factors."
There's no context to this shot identifying it as being representative of the subject's lifestyle. It's also, no offense, a bit sloppy with the grey thing centre left drawing the eye and the slightly awkward leg.
What I'd be looking for, when asking a photographer to present me with a lifestyle shot; is an intimate understanding and sympathy with the subject and their environment. For a kid, put her in a playground, school, party or some other event and lend weight to the shot with a message about the background. "Girl in park with red umbrella" isn't lifestyle.
Sorry, I must need another coffee, but hopefully this is helpful?
