A look down St Martin's Lane, London

I've been going through some older sketchbooks recently for something I'm working on, and came across quite a few drawings (unhelpfully not dated by me, but perhaps around 2000) that suddenly made me quite nostalgic about the good old 2B pencil.
I've gone on and on about my love for the humble, high fibre option pencil before, so I won't do it again, but... I just wish pencil drawings felt a bit more permanent when they are finished. Fixative or no fixative, they seem temporary in a way pen drawings don't.
