It's spring in Australia, so I'm on a lookout for swallow nests and swallow babies. I love these little feather balls, and I have multiple sketches and paintings of them. This particular piece is actually very old, sketched back in 2011, but last year I went over it and added a lot detailing and shading to bring it more to life, so it's ready for a home.
An 8 x 10 dark brown or black frame would work really well for this.
