I appreciate the critique, as this was my first attempt and I made it in about 15 seconds. The obvious fakery notwithstanding, I think it looks better than several of the porkers in Meldrum's collection, and I'm sure with a decent backstory there are plenty of 'footer's who'd consider it authentic.
The actual backstory is that we found a nice muddy patch with some prints and I challenged some of my Ornithology students who are also taking Mammalogy this semester to identify the print-makers. We had pet dog, raccoon, white-tailed deer, and opossum recorded in the mud. On the spot, I decided to show them how easy it can be to make a footie-print. From me deciding to try that to me snapping the photo, approximately 1 minute had elapsed.
