Truly enjoyed seeing all the details. Also: what a difference it made to use the pencil recommended in the course; I've struggled to find a pencil I like to draw with, and this was great.
The bird's feet were challenging for me -- proportions, angles.
I did not realize how streaky the breast of the bird was until I started to draw it; or how very distinctive the different kinds of feathers are (nice to be able to zoom in to see the details)
This is very much an advantage when learning about a bird.
