Most of the artists I work with ink themselves, so I don't usually see traditional pencils from them. Instead, they sometimes send over very rough pencils before going straight to inks. These rough pencils are great to look at because of the life and energy they have. Here are two pages of roughs from Jon Sommariva, from Gemini #3.
And here are two pages of roughs from Noble Causes #38, by Yildiray Cinar. Yildiray has a real love of sound effects, so in order to get the exact look he's going for, he's started drawing them in himself, rather than have them done later by our letterer.
