Recently finished drawings

All of these drawings were finished between 11/12/2014 and 12/05/2014. I borrowed a good camera, so, hopefully, the focus is better than what i had been posting. However, it wants to set the off-white or tinted paper as being mid-grey tone. I am not sure who to correct for this on a digital camera. ( I know how to do it on an old 35 mm camera....I am a dinosaur.)
