The Cluster: pen & ink in-situ

This illustration was not a commission, I am using this building to showcase different ways I could illustrate a property. This illustration shows what can be achieved with a pen & ink drawing in-situ. Because it was a private, internal space, it was possible to complete the whole illustration at the venue with no time limits or restrictions of access.

If the viewpoint is in the public sphere with restrictions, then I would do as much of the compositional pencil sketch stage and inking stage as possible and take photographic reference to complete the illustration back at my desk. The composition stage is the most important to get the feeling of an in situ sketch.
