Which of the media you have experimented with did you find the most expressive?
From experimenting with the different colour media in this exercise I would probably say at this stage that the oil pastel is the most expressive. Oil pastels seem to allow more sketchy fluid strokes and seems to work well with all the techniques that I have practised so far.
Which medium do you think lends itself to more detailed work?
From what I have seen so far I would say coloured pencils as well as ball point pen but then again I do not think I have worked with nib pens and ink enough at this stage to dismiss these as a medium for more detailed drawings
