Weight or Mass

f/3.5, ISO 500, 1/320, 50 mm

We were tasked to take a photo of something that had visual mass. When first looking at the prompt I was unsure of how I would be able to show visual mass in a photo. But while I was sitting in my friends car, I saw a USPS truck and felt that it stood out against all of the other cars. So with centering the USPS truck in the middle to really draw your eyes to it I felt that it held a lot of visual weight to it.
