My Pinhole Photography

This is my first pinhole picture inside of the atrium, this picture had an exposure time of 30 seconds.
I really like this picture because the lines are crisp and sharp. 

This is my second pinhole picture that I took outside of the benches and trees, this had an exposure time of 20seconds.
This picture didn't turn out as well as the first one because I was pointing my pinhole camera in the direction of bright sunlight so this needed less exposure time.
