Over at Heroes Realm there's little piece by artist Mark Brooks on how he went around making the cover to Araña #4. Fairly informative little peice if you want to learn more about the artistic process in which a comic is made.
Also if you just can't get enough Mark Brooks art take a spin by Brooks' Deviant Art Page, to see a nice gallery of illustrations past and present he's done, featuring not just Spidey & Arana but also various Capcom & Transformers characters.
