graphite sketch corelli face

‘idea, corelli painting’

Starting a big project, I collect and sort photos. I want to create a tribute to the Italian tenor Franco Corelli; career, 1950-1974. Sketching like this helps me focus. It is based on the earliest professional photo portrait of him I can find. The effort feels like thinking with a pencil. I also listen to his final concert and his performance in ‘Turandot’ for stimulation.

. . .How might I create something original without studio access?

1. Do YOU collect-sort-sketch-stimulate too?
2. Or do something else to plan a large work?
