Cawcus~Developing a Concept

I've been observing a flock of crows that have been visiting the park this winter. Actually I think they may be ravens because they are huge. I keep a tripod in the front window and take photos whenever the opportunity presents itself. The title is a play on words, the word being caucus (link). Here I've gathered various sketches of crows, some from my own photos, some from imagination and others from images online and created a storyboard of sorts. The sizes of the birds in relationship to each other and within the composition are off and the placement is still a work in progress but my ultimate goal is to create the illusion of a town hall meeting or 'crow caucus'. Because these birds seem to always be communicating with each other in some fashion, seemingly having discussions, the idea just naturally evolved.
