Your midsection is absolutely normal. I think you look fine but since you came for advice I'd say squats, squats, and more squats.
You should start to lift some weights. Squats will give you some ass and help with the legs too. As for the belly, I assume you'd need to loose at max 5kgs to look really good. If you start a weight lifting routine you could even achieve the desired look without changing your body weight at all.
What is it that you are trying to work on?
If you want to work on toning your muscle structure, lifting some weights will probably help you more than any cardio. However, if you are looking for other health benefits aside from just appearance, I'd recommend jogging. You'll find it to be addictive. :)
