These are all done on 5x7 (I think?) paper with graphite pencil, white gel pen/white paint markers, and colored pencil for the three color ones. The photos are kind of bad, I don't have an actual scanner at my disposal anymore. The bottom right one is especially bad, but it's hard to capture it with a photo. Part of what's cool about graphite on black paper is how it changes lightness depending on the viewing angle, to the point where the graphite becomes invisible at certain angles, leaving just the white gel pen visible. It's a pretty neat effect, and I promise it looks a lot better than in the photo.
