A very nice image representing world cooperation, this is most likely for some sort of charity organization. The vector image is cleaner and therefore more professional looking, which in turn grants more respect and attention. The green man on the bottom’s head is much larger than the others… I think it’s an alien… but a peaceful one by the looks of it.

Here is a good example of how a picture like this might come out once vectorized. Photo quality images will always look different once vectorized, but the artist has used different effects including bitmap effects to replicate the original as close as possible. There are various reasons people have this service done, such as: printing purposes; they like the style/look of the vector art; it is easy to manipulate; etc.
If you have a photograph (of a person or otherwise) that you would like to get vectorized it is always best to get a quote first.
