i have a headcanon that sherlock is a wonderful artist. and before he meets john, he makes money on the side by providing beautifully detailed technical drawings to museums to display with their exhibits. but after he meets john, he begins to draw only the man. he fills sketchbooks with graphite images of his figure, covers canvases in the colours of his eyes and hair, and lets ink flow over pages to create the man’s face. john becomes his muse, and the longer he goes on capturing the man however artistically possible, the harder it becomes to hide what he is doing. and eventually, when john finds sherlock’s hidden collection of artworks of him, he is blown away by not only his flatmate’s talent, but by the fact that he is so entranced by little old him. and that is when he first starts falling for sherlock.
