The top two drawings were done with graphite, the rest are ink using a new brush pen that my husband picked up for me. This is THE best brush pen I have come across. You can get incredibly fine lines with it, (which has been my main complaint with the majority of commercial brush pens). I love to use an ink well and series 7 brush when in the studio, but this is so much easier to tote to the many figure drawing groups I go to. A lot less clean up as well. My husband, Greg Baldwin (of Creaturebox) gives the details about the maker of the brush pen and describes how he is using it on his blog which you can check out here. We discovered that if you order it from the UK, you get extra refills and it's slightly cheaper (even with shipping). I hope some of you will give it a try.
