Mate, dun worry,.. P&S cannot achieve the bokeh behind the girl. It would be all sharp because if the large DOF. You must also understand that it's not just the camera but also the composition that plays a part to getting good pics.
Firstly, your pics is alittle blur. Can be fix by using a faster shutterspeed, higher ISO, bigger aperture. Aim between eyes and shoot.
Secondly, the lack of expression which makes it look like a snapshot. First shot, open mouth, lazy eye contact. 2nd shot, no eye contact. Lack of catchlights. The trick is to shoot alot of pics, if you are lucky, you should have a couple of good ones. Learn to see the light and use it. Post process also needed to remove the mosquito bites and enchance the colors/constract.
