I have usually sketched from photos, so I have a little more comfort there with a still image, and a pencil. The beak was a surprising little challenge - as it was initially wider than the little pincer-like warbler feature I was first going for. I think the thing I really enjoy about journaling over photographs is the labeling of other things - like the lichens, and the tree species (even if unknown). Adding features like time/date/weather, maybe the trail etc. I am most nervous about the real-life drawing in situ - the figure/motion drawings is something I've never done.
