This is just an experiment for my sketchbook portrait, using Dr Martens liquid watercolours (because they're hyper bright) and oil based pitt pencil (because it's proper black). I think it worked.
I drew Nicki Minaj from a picture in an old issue of Wonderland. Once I start drawing, it often amazes me how crazy celebrities faces are and Nicki's is just about as nuts as she is.
I often instagram things-in-progress, so follow if you're interested in seeing that kind of stuff I'm @abihey - FOLLOW!
