A Study in Scarlet and Blue is a fan-made AU* Spider-Man webcomic made by Meg Syverud (who also does the very good Daughter of the Lilies). I like this one because Meg has a real feel for how Spidey moves and talks; her portrayal of him is very organic. I also like the B&W format. It feels clean and elegant.
Check it out.
