That happened to me once--We went to a museum and I touched one of the "fossils" (That I wasn't supposed to touch but I was a tiny and rebellious child) and it was just plastic// Also I have a suggestion for your art? Try to make the noses lower, as the tip of the nose should be under or near the middle of the eyes. I'd also advise adding arms to spice things up so the material doesn't get stale.
