What if you don't spot any details that are obviously wrong, but still think something is amiss? Conversely, what if you can't pinpoint any masterful details, but you still think you're looking at a masterwork? According to author Rachel Polinquin, the answer to both questions is simple: Trust your instincts.

"One of the questions I often get asked is how do you know if it's good taxidermy or not?" Polinquin says. "It's obvious what good taxidermy is! We have an innate knowledge of what an animal should look like. Animals don't walk around with great gobs of glue or wax or broken ears. If it looks like the animal could just sort of shake itself awake, then it's great taxidermy."
