Autumn's Bounty - Milkweed Seedpods

Week 3 of Fundamentals of Natural Science Illustration: Autumn's Bounty focused on seedpods. I was attracted to one particular branch of milkweed seedpods because the inside of the pod was tinted pink.  I have collected many milkweed seedpods for papermaking and have never seen one tinted like this one was. I thought it was stunning! Here is my rendition of it.
