Animals for a smaller ark

I generally like to whittle and carve smaller items.  Following up on a previous post about carving a small horse, I am doing about 20 pairs of smaller animals for a smaller ark.  After I finish the animals I'll size the ark to the animals.

Here's a sample of some of the animals.  The pocket knife is included as a size reference.  The animals were carved with a cheap rotary tool and a sanding sleeve.
