Drawing Class Art

I had a drawing class this semester for my Graphic Artist degree. These are in blacks and greys and white and colored charcoal. I’d like to hear which one you like the best. I am to pick my own creation as my final exam grade but can’t decide.My next semester has a digital photography class and the rest of the classes are within the Adobe Creative Cloud suite. Illustrator, InDesign and Photoshop. #artwork
