The poll is still going, but the flying stamps is definitely ahead. I was going to make the winner unlock at $1500 and it's already almost there! Second place is still close, so I went and did the ones that were close when I checked earlier which was the foil designs. So here's the flying animal stamps and the foil designs with the animals labelled. I might still edit these some but here they are.

I went and included some fossils in the area to fill in the dirt in the underground scene.
