'Oh I do like to be beside the seaside...' work in progress

This is the final pen sketch that I place under my watercolour paper for tracng through on a lightbox. The 300gsm paper is very thick, so the 'pencil' needs beefing up in ink in order to see properly. Appropriately the seagulls were crying out as I painted this one last night (I live by the sea), adding an authentic atmosphere!
