Bricks in pastel

A few minutes to spare and needing to draw something..anything. As we were tidying up we found some bricks, which found their way onto my table, so they were it. I thought I'd play with my oil pastels and this is the result:

I'm pleased with how it's gone, although the top brick looks a little like it's got a long red nose!
I was trying to follow the suggestions of Susan Sarback in 'Capturing Radiant Colour in Oils' - blocking in planes of colour, then modifying them to relate to each other, varying them across the surface. I think the lucky coincidence of the turquoise table being complementary to the yellow ochre bricks has something to do with the whole thing too....must work more on colour theory......
