Creative Sketchbooks course - module 2

I have just completed module 2 of my creative sketchbooks course. I learnt quite a lot in this module, particularly about the use of pastels and oil pastels. This picture is of one of the pieces of work I completed for the module. It was done by using an aperature to either as a negative or positive image. I really like the subtle effect you can get with the pastels yet at the same time retaining a very definite image. I can see lots of potential for this in the textile world.
