Testing my new friend

Loving my new Nikon d5200 and i've been taking photos as much as possible without looking like a bit of a wanker. I'm still a bit embarrassed taking photos in public and want to work my way into taking photos of people but i'm still not exactly sure about how i'll go about asking people if i can take their picture or if i'll simply take the photo and then ask if i can keep it.

These are just a few tests and such i've done with my new camera.
