Using my viewfinder I selected four viewpoints at a local farm for quick sketches, with me standing in a central location and turning approx. 90 degrees each time to find a different focal point at north, south, east and west. The sketches took me longer than 15 minutes each I recall. I chose the farm as it is a large area with different focal points at every turn including trees, fences, barns, animals.
I worked with a mix of charcoal, charcoal pencil and conté crayon.
I feel with the above image I happened to get a feeling of depth. The chicken in the middle moved off quickly so is not a very accurate depiction.
This image above is the one I decided to use in the future exercise - Plotting space through composition and structure.
