Polaroid Pics...Fail

I found this jewel at Goodwill when I lived in Seattle for $5.99. I recently found a company that still makes film for the polaroid land camera. I have been so excited to see if the camera even still works. Here have been my results.

It was a little discouraging. I am unsure if it is the film, camera, or photographer. I can't figure out how to set the L/D dial. There is so much pressure to get a good picture. I only have 8 chances to get a good shot. I have one more chance to capture and set my exposure. I am waiting for the right moment.  Are there any polaroid junkies out there that have any tips?
