To set up a scene quickly by literally throwing things together is some kind of skill.
Some can do a decent pic within 20 Minutes (with little to no postwork) and other maybe can not do it for various reasons.
If somebody throws stuff together you could still tell him/her that item X would fit better than what he used or that the color Yab doesn't match with whatever else color.
After some practise the quick pictures should look better then.

That is if the person wants to combine fun with practise.
