Playing with aperture

I've been experimenting with the aperture on my camera. Had a slight mishap where I got the tripod stuck on the camera and badly scratched said camera trying to get it off. Oh well. It's on the bottom anyway. Above you can see my efforts. I've been going through my3boybarians' photography course (free) '31 days to a better photo'. It's really great for refreshing my photography knowledge.

I used a 50mm lens for these photos.
