The ten minutes flew by and I struggled to draw the model’s shape , let alone tonal contrasts. After 5 attempts this did not seem to get any easier so I gave myself a little longer for the final sketch.
When using chalk pastels the chunky stick encouraged larger, bolder marks and lines and covered a larger area of paper more quickly, this allowed me the time to work on tone. I am pleased with the chalk sketches and feel I have been able to create a sense of weight and proportion but I need to work on describing a sense of 3-dimensional form.
