Techniques - Oil Pastel

Below are images taken of work completed during a workshop exploring the technique behind the use of oil pastels, a medium I though appropriate due to is close resemblance to the medium used by the artist Rossetti, although what differed and caused my decision to not use this medium for any further works, was the difficulty I found in creating detailed and correct shapes. The medium was effective for creating full and even tones with a smooth, texture-less surface.
