I have not drawn in a while, so I was a bit nervous, but once I started it felt good. The hard part for me are the feathers, especially the very fine, fluffy ones on the upper back. You definitely pay more attention to the details when you have to draw something - especially the color combinations in the feathers. I only drew this with pencil, though, so I could only hit the light and dark tones. But I like that drawing forces you to spend a lot of time on the details, this could really help you remember how to identify a species.
